Modbus Register Types

Discrete Inputs (R41,070)

This table shows the current status of the discrete inputs. Only register 41,070 is used.

Relay Outputs (R41,080)

This table shows the current status of the relays. A reading of 0 means that the relay function is not asserted and a 1 means that it is asserted. For example, a 1 for a pump relay means that the pump is running.

Values are written to control a relay only if the Relay Control Function (P111) is set to communications (65). See Relay Function Codes (P111 Only) on page 110.

mA Input (R41,090) [MR 200]

The mA input is scaled from 0 to 2,000 (0 to 20 mA multiplied by 100). P254 displays the value of the input. This parameter is indexed by the input number.

mA Output (R41,110-41,111)

The mA output is scaled from 0 to 2,000 (0 to 20 mA multiplied by 100). This is displayed in P911.

Pump Control (R41,400 – R41,474)

Only relays set for pump control (P111 = 50 to 52) are available. These registers have no effect on relays programmed for other uses.

Pump ON Setpoint (R41,420 – R41,425)

The ON setpoint level (P112) for the referenced pump relay.

The setpoint is scaled from 0 to 10,000 (0 to 100% of span multiplied by 100). So 54.02% is shown in the register as 5402.
