Chapter 2 – Network Electrical Systems RS-485 MS/TP Communications Network Loading The RS-485 specification allows 32 full load devices on a section of network cable before a repeater is required. Most Siemens BACnet nodes are 1/8 load devices, so, in theory, you could place 256 on a network section. Response times normally limit the maximum number of devices on a network to lower values of around 96 devices.

Chapter 2 – Network Electrical Systems RS-485 ALN and FLN (P1) Communications Wiring on Structured Cabling HSTIE Usage The number of High Speed Trunk Isolator Extenders (HSTIEs) on a logical RS-485 ALN or a logical FLN trunk is directly related to the total trunk length, type of trunk wire used, and the time delay allowed by the network protocol. Trunk cabling causes bit distortion that limits the total trunk length to the distances listed in table Distance per 2-wire Trunk Section.

Chapter 2 – Network Electrical Systems RS-485 ALN and FLN (P1) Communications Wiring on Structured Cabling Use of Shielded and Unshielded Twisted Pair Cable Shielded Category 5 cabling is used where excessive noise is expected on the information system cabling, for example, when it is near a high-power transmitter. In these cases, the same shielded Category 5 cable will be used for the RS-485 ALN and FLN trunks.

PAGE 61
Chapter 2 – Network Electrical Systems LONWORKS FLN Communications Wiring Nodes per Subnet/Network Any device that contains a Neuron ID (and therefore a unique address) is counted as a node. Devices such as repeaters and network terminators do not have addresses and thus are not counted as nodes. Electrical Loads The number of electrical LonWorks bus loads allowed per segment is 64. All devices, with the exception of the network terminator, count as one electrical load.
PAGE 62
Chapter 2 – Network Electrical Systems LONWORKS FLN Communications Wiring NOTE: Sensor wiring (the wiring from the LTEC to the LTEC room temperature sensor) must be included in the wire length calculations for a segment, because the sensor wiring carries the network signal. Fig. 36: Determining Network Length—Example. Network Wiring Only approved cables may be used for network wiring. These include unshielded and shielded (where specified) to conductor 22 AWG Level IV cable.

Chapter 2 – Network Electrical Systems LONWORKS FLN Communications Wiring Each network segment (1 without repeater, 3 with repeater) requires a pair of terminating resistors (part number 587-649, packs of 100) wired in parallel anywhere on the segment, at the field panel, or at the repeater. See LonWorks FLN Network Terminations [➙ 63] in this chapter for more information on segment termination. Fig.

Chapter 2 – Network Electrical Systems Power Trunk Guidelines Power Trunk Guidelines A Class 2 circuit, as defined in the National Electrical Code (NEC, operates at less than 30 volts AC (Vac), and is limited to 100 volt-amps (VA) or less. Class 2 circuits are granted special exceptions in the NEC for installation wiring, making it unnecessary to use conduit in most applications.
PAGE 65
Chapter 2 – Network Electrical Systems Power Trunk Guidelines ● ● For 24V power trunks, each transformer circuit must be protected by a single fuse or integral circuit breaker rated 4 amps or less. This protection is required even if the transformer is rated at 100 VA or less. A fuse block for the trunk fuses may be required by local code. CAUTION Always check local codes to determine whether there are differences from the NEC.
PAGE 66
Chapter 2 – Network Electrical Systems Power Trunk Guidelines Fig. 38: Power Trunk Layout, Class 2 Circuits. CAUTION Circuits connected to transformers rated over 100 VA must be treated as Class 1, that is, in conduit, separate from ALN, FLN, and point wiring. When power requirements exceed 100 VA, it is recommended that multiple transformers 100 VA or less be used, rather than a single transformer. Fig. 39: Power Trunk Layout, Class 1 Circuit.

PAGE 68
Chapter 2 – Network Electrical Systems Power Trunk Guidelines Step 1 - Determine the VA Rating for Each Controller VA ratings can be found under the heading Power Source Requirements in the chapter that covers each type of controller. If future options are to be installed, the VA rating of the affected controllers can be increased. Therefore, if future upgrades will be implemented, include their power consumption in your calculations. Example Controller Type VA Required C1 DXR2.
PAGE 69
Chapter 2 – Network Electrical Systems Power Trunk Guidelines Step 2 - Determine the Number of Power Trunks Required Use the following steps to select and locate the transformers. 1. Based on the total VA, determine the transformer(s) you will use to supply power to the trunks.  For example, if the total VA required for all controllers is 129.3 VA, you could use any combination of inherently limited Class 2 transformers that supply the required power.
PAGE 70
Chapter 2 – Network Electrical Systems Power Trunk Guidelines 1 × 20.0 VA 3 × 19.4 VA = = 20.0 VA 58.2 VA 228.25 VA 2. Determine the minimum number of power trunks you will need: - Minimum number of trunks = 228.25 VA ÷ 100 VA = 2.28 - Since this number is greater than 2, it will be necessary to use a minimum of three power trunks. NOTE: This does not imply that transformers totaling 300 VA will be required.
PAGE 71
Chapter 2 – Network Electrical Systems Power Trunk Guidelines NOTE: Different controllers have different power ratings. You may need to calculate the voltage available at the last controller of each type on each wiring run. To calculate these voltages, you must know the following: - The length of each leg of the wiring run. - The VA rating for each controller on the wiring run. - Which devices pull power through each leg. 3.
PAGE 72
Chapter 2 – Network Electrical Systems Power Trunk Guidelines Example 1. Configure the power trunks so that the total VA rating of all devices does not exceed 100 VA per trunk. (Many configurations are possible. See Figure Completed Example Layout for the configuration used in this example.) – – – Trunk A: (1 × 5.7) + (3 × 13.6) + (1 × 32.75) = (1 x 15 = 88.55 VA) Trunk B: (1 × 27.9) + (1 × 20) + (2 × 19.4) = 86.7 VA Trunk C: (1 × 27.9) + (1 × 19.4) + (1 × 5.7) = 53.0 VA 2.
PAGE 73
Chapter 2 – Network Electrical Systems Power Trunk Guidelines By similar calculations, power drawn through the remaining legs is: Trunk B Trunk C Leg 1 = 66.7 VA Leg 1 = 42.6 VA Leg 2 = 19.4 VA Leg 2 = 33.6 VA Leg 3 = 47.3 VA Leg 3 = 27.9 VA Leg 4 = 27.9 VA ◈ Determine the voltage drop for each leg:  Voltage drop = (total VA)/24V × 0.005 ohms/ft × distance in feet  Where: 0.005 is the resistance in ohms/ft. for a pair of No. 14 AWG wires. Trunk A Vdrop (Leg 1) = (74.75 VA / 24V) × 0.

AEM/AEM100/AEM200 Devices that allow APOGEE field panel networks to communicate with the Insight workstation across an Ethernet network. The APOGEE Ethernet Microserver (AEM) operates on a 10Base-T connection, but can also be routed across low speed networks (for example, across Frame Relay).

Glossary Class 2 Power Source, Inherently Limited An inherently limited Class 2 power source has some form of current-limiting characteristic designed into the product. Sources of this type are often protected by a current-limiting impedance or embedded fusible link, but other methods are also used. As long as the current limiting is an integral part of the power supply, it will fall into this category.
