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.
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… read more →
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… read more →
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… read more →
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… read more →
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.
Yes. AC powered expansion units can be connected to DC powered CPU’s and vice versa. Power to ALL units MUST be turned on at the same time otherwise communication issues… read more →
In the main, Yes, except for the Ethernet CPU’s which can be programmed via an Ethernet cable. There are two types of programming leads for our CPU’s: 1. RS232 Cable… read more →
The main reason for this is that you are probably using the latest version of the software but your CPU has an older version of firmware. Use the firmware updater… read more →
There are a number of things that would cause this issue. If it’s the first time you have used your USB cable with the PC, please ensure you have the… read more →
Yes, you can achieve this through the programming software by selecting “Tools -> Edit Cover HMI”. Only the first two lines of the LCD can be changed but you can… read more →
