Is it possible to add extra IO to the CPU?
Yes. Most of the CPU’s IO can be increased by the addition of expansion units. The exception to this are the PR-6 and PR-12 CPU’s, which are not expandable.
Which expansion units work with which PLC CPU’s?
NOTE: The Economy 6-series and Standard 12-series CPU’s can not be expanded! For the ELC-18, ELC-22, ELC-26, PR-12, PR-14, PR-18, PR-24 and PR-26 CPU’s then you would use the expansion modules whose part number begins ELC-E- and/or PR-E-. For the EXM and ELC-12 Ethernet CPU’s, you require the expansion modules whose part number begins ELC12-ERead More
How many expansion units can be added to a CPU?
CPU’s that are expanded by using the PR-E Series expansion units can have a maximum of 16 expansion units per CPU. CPU’s that are expanded by using the EXM-E Series expansion units can have a maximum of 8 expansion units per CPU.
How do you change an expansion units ID?
By default every expansion unit out of the box has an ID of 1. The ID can be changed by changing the DIP Switches hidden under a plastic cover on the side of the expansion unit.
I have changed the ID of my EXM-E expansion unit but the CPU won’t communicate. What’s wrong?
NOTE: All expansion unit addresses MUST be UNIQUE and MUST be set before applying supply to connected CPU! Don’t panic, there’s nothing wrong! By default the EXM and ELC-12 Ethernet CPU’s have their COM ports configured for an RS485 expansion unit. To enable the CPU to use EXM-E expansion units you need to enable theRead More
Once expansion unit ID’s are set, do they need to be connected in order?
No. It does not matter which order you connect the expansion units to the CPU. All that matters is they must have unique ID settings.
