3 Addressing Overview Addressing Overview All the memory used for external I/O processing and internal data processing has always both address and data (the content). Addressing space is classified as R, L, M, K, F, TC, and W. These letters are used to designate a specific area in memory as shown in the following table. Memory areas Addresses Description R000.0 to R127.15 • Local I/O memory area that can be set when configuring I/O module. • 2048 points, 128 words R640.0 to R127.
N The R, L, M, K, F, and TC areas can be used for both bit and word addressing. N The W area can be used to process word data only. N The L area can be used as internal contacts. N Keep contact (K), data register (W), and counter's preset value register retain their last values before power was removed. Cleared when a new program is downloaded. Bit and Word Addressing A bit address is composed of a character (R, L, M, K, F) that identifies its type, a five digit word address (0.0 to 127.
Double Word Addressing Double word addressing is same with word addressing, except that 32-bit data is referenced by the specified address and its next address. The type of instruction used determines which addressing, word or double word addressing, is applied. For comparison instructions, the programmer must be in “Double Mode” to enter a double-word comparison.
Absolute Addressing In LDR, DLDR, STO, and DSTO instructions, an absolute address is used to indirectly reference a register or to utilize the built-in communication port. Classification Register address Absolute address Absolute address Register address Classification Dec. Hex.
I/O Addressing Addressing is based on the location of the module. Example 1: 8-slot system Slot No.
Occupied I/O points by module (unit: word) The table below shows the occupied I/O points for each module when the memory space is allocated automatically by the system.

Address (register) Address refers to the location of memory being used. It can refer to the external I/O module and internal memory. An address is categorized into 1 bit, 16 bits (word), or 32 bits (double word). Bit A bit is the minimum module required for calculation. It can be either On (1) or Off (0). Byte A byte is made up of 8 bits. It can hold data values from 0 to 255. In base 16, or hexadecimal, a byte can be expressed as 0 to FF. You cannot have a value greater than 255 when using one byte.
BCD (Binary Coded Decimal) BCD is used to express a decimal digit (0 to 9) using 4 bits. Conversion of BCD values can be done in hexadecimal calculations. Example: 59 (BCD) = 59 (HEX), 32 (BCD) = 32 (HEX) Flash ROM It refers to a ROM (EEPROM) that stores programs. Since its contents can be deleted periodically, it is frequently used for equipments that deals with programs such as a PLC.
• For bit operations, such as setting, resetting, shifting, or rotating Use the M, K, and R area. You cannot perform bit operations in the W area. • When you want to refer to or modify the set value of the timer or counter. Refer to or modify W2048 to W2303 or SV0 to SV255. • When you want to refer to or modify the present value of the timer or counter. Refer to or modify the address area from W2304 to W2559 or from PV0 to PV255. The value holds true in STOP (PROG.) state in this area.

Installation location Be sure to maintain a sufficient distance from wiring ducts, and other machines below and above the module for proper ventilation. Do not install the modules stacked up or horizontally. Doing so will prevent proper cooling of the module and cause overheating inside the PLC (programmable controller). Do not install the module above devices which generate heat such as heaters, transistors or large scale resistors.
Avoid installing the module in the following conditions • Ambient temperature outside the range of 0 to 55 °C • Ambient humidity outside the range of 30 to 85% RH • Sudden temperature changes causing condensation • Inflammable or corrosive gases • Excessive airborne dust, metal particles, salinity • Benzene, thinner, alcohol, other organic solvents or strong alkaline solutions such as ammonia or caustic soda • Excessive vibration or shock • Direct sunlight • Location near high-tension wires
N It is recommended that you use crimped terminal for wiring. N Open type terminal N 7.0mm or less Circular terminal 7.0mm or less Φ 3.7 to Φ 4.3 hole Use 2mm2 twisted pair cable or larger • Use power supply wire that is thicker than 2mm2 to minimize voltage drops. • Use twisted pair cable to minimize noise effects.
Grounding Ground the PLC for noisy environments • Connected to the metal part of backplane, the frame ground terminal is connected to a solid earth ground. • Use ground wires with a minimum of 2mm2 and the triple grounding connection which has a resistance of less than 100 Ω. • The point of grounding should be as close to the PLC as possible and the ground wire should be as short as possible. • If two devices share a single ground point, it may produce an adverse effect.
Input and Output Wiring Input wiring Checkpoints for input module wiring There can be limits on the number of points that can be simultaneously turned on, based on the module type. Check such limits in the specifications of each input module. In particular, be careful when using in high ambient temperature. The connection method for each type of input device including sensor is described below.

Appendix Communication Protocols The communication protocol of NX-CPU700p PLC provides a complete method of communications between the graphic consol programmers (WinGPC) and the PLC by controlling programs, CPU status, and I/O at user’s convenience. The user can easily expand the capabilities of the overall PLC system by communicating to the PLC using a variety of peripheral communications equipment in accordance with the following communication protocols and procedures.
Communication Protocols Step 1-Q Query Query Q (Query) is a signal sent from the peripheral devices to the PLC after setting the network ID number and the function code for the PLC to communicate with. Step 2-QA Query QueryAcknowledge QA (Query Acknowledge) is a signal sent from the PLC to the peripheral devices, indicating that the Q signal from the peripheral device was received.
When several CPU modules are connected to one communication network, they must use individual ID numbers. The PLC’s network ID number is configured using the WinGPC. Communication steps The NX CPU can support 2-step or 4-step communication methods. The communication methods are easily distinguished each other by selecting and sending the function code of the Q frame. Even for the 4step method, the 2-step method can be used for the repeated function.
2-step communication method No communication error Peripheral device PLC When R is not received 3 seconds Peripheral device PLC Response to repeated function code Peripheral device PLC 4-step communication method No communication error For the internal processing of the PLC CPU send RR at least 5 msec after receiving QA.
Function codes included in the query Each function code is 1 byte. When the PLC receives a query (Q), the function code of the final response (R) is formed by adding $80 (hex) to the function code sent by the query. The value added to the function code sent by the query differs for 2-step and 4-step by $20 (hex). The function code of the R message can be used by the peripheral device to verify that the correct Q message has been received by the PLC.
Cyclic Redundancy Checking (CRC) The CRC is a 2-byte checksum code attached to the end of the message by the sender to check if the communication frame is transmitted without error. The sender calculates the CRC when it sends one-byte message, and the receiver should also calculate the CRC from the data of the message.
Structure of Communication Frames The function code is explained with the example of Query and Response frame based on the 2-step communication. Query (Q) and Response (R) frame DA SA Function code Length Information CRC L Length of information area (byte) CRC H CRC-16 code (2 bytes) 1 to 255: 1 to 255 bytes 0: 256 bytes The frame is sent from SA to DA.
Read bits Read the content of the bits (R, L, M, K, F, or TC) assigned to the absolute address. Can read n consecutive bits (On/Off). Query (Q) frame DA SA $21 $03 BAS L H N CRC L H Number of bits to be read Length of information (byte) Absolute bit address (address of first bit to read) Refer to 3.3 Absolute Addressing Ex) K127.
Write bits Modify the contents of the bits stored in the absolute address (R, L, M, K, F, or TC). Change the bit state between On/Off. Can change multiple consecutive bytes. Query (Q) frame DA SA $22 N Base L H Base+0 bit value Base+N+1 bit value Base+N-3bit value - L CRC H To turn On the desired bit value from the base, enter $FF. To change to Off, enter $00. Absolute bit address (starting address) Refer to Absolute Addressing on Chapter 3.
Write words Change the content of the words (R, L, M, K, F, or W) assigned to the absolute address. Can read n consecutive words. Query (Q) frame DA SA $24 Base L H L Base+0word L H - Base+1word L H L CRC H n word values from the base words requested by the Q. Length L = Nx2+2 Response (R) frame DA SA $A2 $01 &00 L CRC H Fixed Read bits and words Read the bits and/or word contents of the assigned absolute addresses.
Write bits and words Read the bits and/or word contents of the assigned absolute addresses. Can read bits and words regardless of their order and location in memory. Query (Q) frame DA SA $26 AO L L H DO Method of assigning bit/word absolute address 15 14 13 0 Absolute Address(Bit/Word) 0 0 Absoulte bit address 0 1 Absoulte word address 1 X Not used Ax=A0, A1, .., An Dx=D0, D1, .., Dn A1 L H - L CRC H Assigning absolute addresses for bits Absolute address for the K127.
