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 use it to place company details, or maybe system details.
Yes, all the CPU’s in our range support Modbus RTU protocol as standard. Ethernet CPU’s also support Modbus/TCP protocol.
If you wish to use the CPU as a Modbus Slave then you do not need to use the Modbus Read/Write blocks. Most blocks and all IO points have a designated Modbus address. These can be found in the software User Manual or if in light-blue text next to the block within your program. SeeRead More
Yes, by use of the Modbus Read and Modbus Write blocks in the programming software.
Yes, the CPU can act as both a Modbus Master and Slave at the same time but ONLY if they are on different communication ports. For example you may connect the CPU via RS232 programming lead to one of our HMI’s, and set it to act as a Modbus RTU Slave. At the same time,Read More
Yes, by the addition of an ELC-Memory module, which plugs into the programming port and saves data to SD card. Some of our CPUs already have a built-in memory card slot! Logging is enabled by the addition of a Memory Write block in your program.
The PRO-RS485 cable plugs into the programming port of any CPU and provides RS485 capability for it. You can therefore use this to provide RS485 communications to CPU’s that do not support expansion modules, such as PR-6 and PR-12 Series. Furthermore, if you use it with a CPU which has a built-in RS485 port, suchRead More
No, not all blocks have a direct Modbus address. For example On-Delay Timer setting does not have a direct address. However, you can use another reference block in your program to store the timer setting such as an AF or Counter block, which does have direct Modbus addresses.
A total of 64 input and output SMS messages can be stored.
A total of 200 phone numbers can be stored in the EXM’s phone book.
The most likely cause of this is that the email server (SMTP) you are trying to use requires SSL. EXM CPU’s do not support SSL so please choose an email server that does not require it.
Before using any of our Ethernet CPU’s we advise using our Device Manager software to configure them for your needs. The Ethernet CPU can act as either a Server (Slave) or Client (Master) and needs setting to how you wish it to behave. Other issues that may cause communication problems are: – Not using anRead More
