Can Your Programming Cables Be Used With Other PLC Brands?
No, all of our cables work ONLY with our hardware.
FAQ
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.
I have an AC expansion unit. Can I connect this to my DC powered CPU?
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 may arise. When expansion units are connected correctly to the CPU, their LED will be Green.
Do I Need a Special Programming Lead for CPU’s?
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 – For transferring program from PC to CPU only. 2. USB Cable – For transferring program from PC to CPU and for updating CPU firmware.
My Program Works Fine in Simulation Mode but Not in CPU. Why?
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 file for the CPU you are using, which is downloadable from our Download area in the Support section.
My PC Software Can’t Communicate with the CPU When Using USB Cable. Why?
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 correct USB driver installed. Use your PC’s Device Manager and you should see something like this: If not download the driver from our Download sectionRead More
Can Analogue Expansion Units be Added to Digital CPU?
Yes, and vice versa.
