5.5 Sample PC Link Protocol Transmission Program

This section presents a sample program that uses PC link protocol transmission.

This program creates increment data within the local port and writes it to the remote port's registers. Next it reads out the same area and compares it with the data within the local port to check that the function succeeded.

This program assumes that the parameter setup request and the operating mode control request (message transmission permission) have already completed.

Local port IP address:

133. 113. 98. 10 (85H. 71H. 62H 0AH)

Local port message transmission UDP port number:

2000

RW090: Execution count specification (1 to 32767)

 

RW091: Operation when a comparison error occurs (continue: 0, stop: 1)

RW092: Transfer register data length (1 to 485 words)

RW093: Write time transfer source register type

RW094: Write time transfer source register start number

RW095: Write time transfer destination register type/read time readout source register type

RW096: Write time transfer destination register start number/read time readout source register start number

RW097: Read time storage register type

RW098: Read time storage register start number

W0991, W0990: Remote destination IP address

133. 113. 98. 20 (85H. 71H. 62H. 14H)

W0992: Remote destination message transmission UDP port number

1025

This ladder program is executed by turn on the R0520 A contact.
