Common Register Setup to Control the
MicroVission (Compressor Control) Via
Communications
Register Setup and Control Scenario
T he MicroVission panel first needs to be placed in
REMOTE mode before the sending the Compressor
Control commands (Registers 40170 through 40182).
To do this, press the START button on the main page and
then the REMOTE button, see Figure C-3.
Modbus Register 40171 - Active Remote Control
Reading this register can be used to verify the Active
Remote Control mode, which was previously setup from
the Configuration screen. Writing to this register can
change the Active Remote Control mode, however this
is not common.
•
0 = None (internal local setpoints will be used to
control the compressor)
•
1 = Direct I/O (hardwired control - via digital inputs.
Refer to wiring diagram)
•
2 = Serial (serial communications via RS485 Modbus
RTU)
•
3 = Ethernet (Modbus TCP or Ethernet IP
communications)
