9.3 PLC Communication
9.3.1 Overview and Communication Specifications
PLC Communication is a mode that performs communication between PV and a specific PLC via a
RS232C or Ethernet interface with an exclusive protocol. The following communications are available.
Data Output
PV500 writes the inspection results and data to the specified register of PLC as the beginning. The PLC does
not need a communication program to receive data.
Switching Product Types
When switching product types, at the timing of TYPE signal input, PV500 refers to the value that has been
stored in a specified register of PLC and switches the product type to the reference number.
When inputting a TYPE signal to switch the type, you can select the value in a register of PLC or the value
specified by the parallel I/O input.
All the commands described in Chapter 9.2 can be also accepted when selecting PLC Communication.
Usable PLCs for PLC Communication
The following list shows the PLC models available for PLC communication via a RS232C or Ethernet
interface.
*1) TOOL port, COM port, FP2-MCU (RS232C communication block), FP2-CCU
*2) Applicable unit: FP-X COM5 communication cassette, FP Web Server 2 unit
*3) Applicable unit: QJ71E71-100 (PLC communication with a PLC unit with a built-in Ethernet port is not
possible.)
• When Baud Rate is "115200 bps", the communication via RS232C interface may not be carried out
stably in accordance with PLC to communicate with. In the case, set Baud Rate to "57600 bps" or
lower.
• PLC communication via Ethernet interface is performed with UDP/IP.
