[PL110] Communication with MCM260-3AD

[user11915]

Im using a PL110 and a remote I/O MCM260 -3AD
How can i read the inputs and outputs of MCM260-3AD?

Hi,
first set communication port of PL110 as master:

Then you have to configure speed, format and time-out in the initialization code:

Then you have to read/write inputs and outputs from/to MCM260-3AD (using COM coil:

Note that every time you insert a COM coil, you have to increase its number manually:

MCM260-3AD will be at default configuration: 57600 Baud, Slave number 1.

In this way you can read inputs from MCM260 like PLC inputs and use MCM260 outputs like PLC outputs.


I attached you the example program I used to take the screenshots:

Hi,

How can the TD900 be configured to read inputs and outputs from a PL110 that is setup in master mode.

The Pl110 is currently running its own system but some of the I/O i need to use to control logic that is being developed on the TD900.

Thanks in advance.

Hi,
for this PL110 configuration it need use the EXP1 because it is setted Slave.

The PL110 is remotely accessible via Modbus RTU to the following registers:

For example if you move a value in to a memory area VW0, the value is avaiable by Modbus Register number 2000.

The EXP1 configuration is available by the SM81,SM82,SM83, etc... that you can setted using the "init" code. (user guide attached)

Best regard.
