4.3 Numbering of Left-Side Modules

After DVPEN01-SL is installed properly, you need to compile the PLC program to control the special I/O

module. PLC offers FROM instruction (for reading) and TO instruction (for writing) to control the control registers

(CR) in the special I/O module.

Numbering of the modules: Every special I/O module connected to PLC MPU has a No. to allow you to know

which module is which when compiling the PLC program. The first special I/O module attached at the left hand

side of the PLC MPU is numbered as K100, the second as K101, the third K102, and so on.
