Adding External Modbus I-O, an example
Follow this procedure to configure remote I-O.
Preset the Modbus I-O module to an address of 80, 81, 82 or 83.
Program the Modbus I-O module to follow the K-Port 2
communication specifications
– 19,200 baud, 8E1
Program K-Port 2 for Modbus I-O
Make all wiring connection between the KCM and the external
modules
Then do the following:
1. Power the KCM and the external I-O modules together.
2. Use the Modbus I-O menu to perform the following set-up.
Note:
If it is not possible to power the KCM and modules together, then once
everything is powered, select <REBIND NOW> parameter to permit
module binding.
3. Verify that at the module preset address, the specific module is
found by name at the parameter <ADDR80-83>. e.g. 80 = WAGO.
4. Open the <DETAILS> menu.
5. Enter module address at <NODE SELECT>.
6. Open <TYPE SELECT>.
7. Note that if the automatic binding was done properly, the module
will have each I-O point already set to a KCM input or output point.
e.g. If the module was a digital 4 input module at address 80, the
screen would look like this:
I/O POINT 1 -> EXTIN1
I/O POINT 2 -> EXTIN2
I/O POINT 3 -> EXTIN3
I/O POINT 4 -> EXTIN4
I/O POINT 5 -> None
I/O POINT 6 -> None
I/O POINT 7 -> None
I/O POINT 8 -> None
8. Go to the specific I-O menu and set the function for each active I/
O point. e.g. set the digital input function for <Clr Tot>.
9. Test the function of each module I-O point.
