6.1 Read Configuration

Device configuration is indicated by 2 bytes.
bit bit bit bit
15 14 13 12
Module # 4
0000 = relays
0001 = analog outputs
0010 = analog inputs
0011 to 1110 - future
1111 = No exp. board

6.2 Fail-safe

Device fail safe configuration uses 4 bytes.
bit15 bit14 bit13 bit12 bit11 bit10 bit9 bit8 bit7 bit6 bit5 bit4
Fail safe timer value 30 to 3600 (seconds)
bit15 bit14 bit13 bit12 bit11 bit10 bit9 bit8 bit7 bit6 bit5 bit4
Analog Output value when in fail safe condition: (mA x 100)

6.3 Configure Analog Outputs Range

rng: '0' – 4 to 20 mA (2 to 10V), '1' 0 to 20mA (0 to 10V)

6.4 Multipurpose command

Multipurpose command uses 2 bytes, and can be used on the following situations:
•
Control all relays of a remote driver (RD-24) device.
•
Control all analog outputs of remote drivers with same value.
•
Control remote drivers with analog outputs and relays with same output values for relays and same output
values for analog outputs.
•
Command to prevent a failsafe timeout when there is no change in the state of the outputs.
