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 : 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 number 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 communication on the connector J1. For the first and last sensor adapter in
a series, their termination resistors must e set to ON. If not, communication between
sensor adapters is not possible.
