IB-23C650M INTRODUCTION INTRODUCTION About This Supplement This supplement provides instructions for installation, setup, and use of the Modbus RS-485 serial communications option available in the MODCELL 2050 Single Loop Controller. Comprehensive instructions covering all aspects of the controller not related to Modbus communication are included in the IB-23C650 User’s Guide.
IB-23C650M INTRODUCTION allows it to be identified by the master. This permits multiple slaves (controllers) to reside on a single Modbus network. The controller can be assigned any address between 1 and 247. Addresses are set in the RS-485 MENU as part of the setup for modbus communication. Address 0 is the “broadcast” address. Only write messages can use it. All controllers process the message, but there is no response back to the host. Other types of slaves may reside on a network with the controllers.
IB-23C650M INSTALLATION INSTALLATION This section provides instructions for making Modbus network connections using either a 2-wire or 4-wire configuration. This information assumes that physical installation and all other electrical connections are being made in accordance with the instructions in IB-23C650. Before making any connections, be sure the controller can support Modbus communications; see the option requirements below.

IB-23C650M INSTALLATION 4-Wire Modbus Network Connections Connections for typical Modbus networks using a 4-wire configuration are shown in Figures 2 and 3. The host device functions as the master and the controllers function as slaves. It is recommended that no more than 32 devices be connected on a single network. The number of devices can be increased by the use of repeaters. When the host is a device such as a personal computer, the instruments and host must have a common ground as shown in Figure 2.

IB-23C650M COMMUNICATION APPLICATIONS COMMUNICATION APPLICATIONS The following are sample applications available with the controller through the use of Modbus communications. The RS-485 MENU is used to set up the controller for these applications. The setup requirements are described in detail in Table 1.
IB-23C650M COMMUNICATION APPPLICATIONS Attributes in the RS-485 MENU permit the supervisory control mode to be indicated via the set-point status display on the front of the instrument. Each of the three characters in the status display is configurable so that the user can choose an appropriate mnemonic to represent the supervisory control mode. A timeout value can be defined for communications traffic to the instrument via the Computer Timeout attribute.
IB-23C650M RS-485 COMMUNICATIONS SETUP RS-485 COMMUNICATIONS SETUP Before starting the communications setup, refer to the Setup Section in IB-23C650 for information about the setup preparation, method, and controls. Perform the communications setup using the RS-485 MENU as described in Table 1. Note: In order to access the RS-485 MENU, the RS-485 Communications Enable attribute in the BASE CONFIGURATION MENU must be set at YES. Refer to Table 1, Base Configuration in IB-23C650.

IB-23C650M BASIC OPERATION WITH A HOST DEVICE BASIC OPERATION WITH A HOST DEVICE This section supplements the Basic Operation Section in IB-23C650. It covers the operational activities related to Modbus communication which are performed in the DISPLAYS MENU. Enabling Write Communication With a Host After completing the RS-485 communications setup, the host can read instrument data when the bus is enabled (see Table 1, Step 9).
IB-23C650M BASIC OPERATION WITH A HOST DEVICE If necessary, the operator can disable the host from writing to the controller. This gives the operator total control of the instrument operation. The host can still read data from the instrument but cannot write to it. To disable the host, access the CMP status display as described in the previous section. When CMP appears, press the DN or UP key to change the status from ENABLED to LOCKED.
IB-23C650M BASIC OPERATION WITH A HOST DEVICE Supervisory Station When the controller and host device are configured to provide a supervisory function, the controller receives its set-point from the host device. The controller executes its PID algorithm in the normal manner, and in general functions the same as a standard controller. This activity is initiated by the host.
IB-23C650M BASIC OPERATION WITH A HOST DEVICE Computer Auto/Manual Station When the controller and host device are configured to provide a computer auto/manual function, the host performs the PID control function. The results are communicated to the instrument and then to the field. This activity is initiated by the host. The displays and control key operation for a computer auto/manual station are as follows: Tag display can be configured to indicate that the host has initiated activity.
IB-23C650M BASIC OPERATION WITH A HOST DEVICE Diagnostic Messages The controller provides diagnostic messages which alert the user to communication problems . The Diagnostic messages are displayed on the TAG line. When one or more unacknowledged messages exist, the red LED on the ALARM key flashes, the message alternates with the TAG on the top display, and the beeper sounds if configured to do so. This activity continues until all diagnostic conditions are either acknowledged or no longer active.

IB-23C650M MODBUS PROTOCOL MODBUS PROTOCOL Communications Speed The controller supports baud rates of 150, 300, 1200, 2400, 4800, 9600, 19.2K, and 38.4K baud. Messages are not buffered. A new message (including broadcast type) will not be accepted until an existing message has been processed and responded to if necessary. Message Response Time The controller typically takes between 10 and 30 milliseconds to respond to a message requesting 10 registers.
IB-23C650M MODBUS PROTOCOL Messages Supported The controller utilizes registers and coils to access information. The following MODBUS messages are supported by the controller. See the Gould MODBUS Protocol Reference Guide dated Jan. 1985 for further detail. Note: 34 In cases where the controller processor is already heavily loaded, it may be necessary to limit the number of registers or coils addressed by any single message.
IB-23C650M MODBUS PROTOCOL Table 2. MODBUS messages supported by the 2050R Controller MODBUS MODBUS Function Message Name Code 2050R Definition 01 Read Coil Status Read "n" consecutive discrete (boolean) points from a specified starting point. The controller returns zeros for points which do not contain defined data and will nak any request for point numbers greater than 9999. See Note, page 34. 02 Read Input Status Same as Read Coil Status.
IB-23C650M MODBUS PROTOCOL Message Formats The following message formats are used to transfer information between the controller and a host. Refer to the message format example for format details.
