MC-3010A/3020D/3030D
This paragraph shows how to set the MC-ANLG Board (24P0115, for MC-3010A),
MC-DIN Board (24P0116, for MC-3020D) and MC-DOUT Board (24P0117, for MC-
3030D).
Rotary switch U18:
Use the rotary switch (U18) to set the MODBUS address with a digit of number from
“0”. When multiple sensor adapters are connected to the MC-3000S, the same num-
ber cannot be used among them. (It is allowed to use the same number between the
MC-3000S and a sensor adapter.)
Jumper block
Use the jumper block J25 to set the termination resistor on/off for the MODBUS com-
munication on the connector J1. For the first and last sensor adapter in a series, their
termination resistors must be set to ON. If not, communication between sensor adapt-
ers is not possible.
