Modbus Register Types
Input/Output (R41,070 – R41,143)
The HydroRanger 200 has discrete inputs, mA inputs, mA outputs and relay outputs. See
below for details for each I/O type.
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 108.
mA Input (R41,090) [6 relay model]
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.
