Parameter

Definition

COMMUNICATIONS STATION ADDRESS—This is a number that is assigned to a controller that is to be used with the communications option. This number will be its address.

COMMUNICATIONS SELECTION

DISABLE—Disables RS-485 communications option. MODBUS—Enables RS-485 Modbus RTU communication port.

IR ENABLE–Disable/Enables IR communications port.

ATTENTION If there are no IR communications transactions for four minutes, then the IR port automatically shuts down. It can be re-enabled by pressing any key on the front panel.

BAUD RATE is the transmission speed in bits per second. This value is used for both RS-485 and IR Communications, but for IR Communications, values below 19200 baud are interpreted as being 19200 baud.

4800 BAUD

9600 BAUD

19200 BAUD

38400 BAUD

TX DELAY—Configurable response-delay timer allows you to force the instrument to delay its response for a time period of from 1 to 500 milliseconds compatible with the host system hardware/software.

Defines word/byte order of floating point data for communications. Byte values:

0 123 seeeeeee emmmmmmm mmmmmmmm mmmmmmmm

Where:

s = sign, e = exponent, m = mantissa bit
0	1	2	3
1	0	3	2
3	2	1	0
2	3	0	1

SHED ENABLE—Disables/enables shed functionaliy. Applies to Modbus protocol only.

SHED TIME—The number that represents how many sample periods there will be before the controller sheds from communications. Each period equals 1/3 seconds; 0 equals No shed.

Note: If ComSTATE is set to MODBUS or MB3K and if SHEDENAB is set to DISABL, Shed Time will not be configurable.

SHED CONTROLLER MODE AND OUTPUT LEVEL—Determines the mode of local control you want when the controller is shed from the communications link.
