TOYOPUC Computerlink — PLC setup

Configure the JTEKT TOYOPUC controller before connecting with any Computerlink library. The Computerlink network settings are common across the supported controllers; only the engineering-tool screens differ, so the guides are split by tool generation rather than by PLC model.

A power cycle is required after every parameter change. Pass the canonical PLC profile explicitly when opening a connection — the libraries do not infer it from the PLC.

These guides use TCP port 1025 and UDP port 1035.

Product family	Hardware	Engineering tool	Setup guide
TOYOPUC Nano	Nano 10GX, Nano 2ET	PCwin2	PCwin2 settings
TOYOPUC Plus	Plus CPU, Plus EX2	PCwin	PCwin settings
TOYOPUC PC10G	PC10G-1SP, PC10G, EF10, 2PORT-EFR	PCwin	PCwin settings
TOYOPUC PC3J	PC3JX-D, PC3JG	PCwin	PCwin settings

Choose a setup guide also lists the example network used by the screenshots, and explains why TCP and UDP need different peer settings on this protocol.
