Glad to learn that the issue has been resolved.

There is a watch dog timer to reset the PLC if the CPU goes hay-wire. In your case, the EEPROM corruption may not be due to a spurious write by the CPU, but an electrical transient via the power supply that may have directly erased the EEPROM.

You can use the "Change PLC ID" button in the TLServer to easily change the ID to any number from 00 to FF.

Is this the first time you attempt to transfer program to the PLC using this computer? Have you previously successfully transferred a program to this PLC?

The "Transfer password" is a legacy feature in the DOS TRiLOGI software but is not enabled in TL5. So if you have never used the DOS TRiLOGI to enable the password then it is unlikely that you should receive a prompt for a transfer password unless your EEPROM has been corrupted or your COM port is not working properly.

Open the "Serial Communication Setup" in the TLServer and type in the following command:

IR*

What do you get in return? The correct response should be "IR01*"  (or other ID if you ever change that). If your response box returned "IR*" then you serial port is not a "real" serial port. What will happen is whatever you type will be echo back to you (try typing your own name). If this is the case, try to use another available COM port. Sometime Windows may report a COM port to TLServer that it cannot use for some reason. So change your com port selection to another working comm port number and re-try.

You mean Negative Temperature Coefficient? You need to built a circuit such that the resistance can be converted into voltage reading and connect that to the PLC's analog input. Then you can compute the actual temperature using either a formula or a lookup table.

What is the ASCII code for the "ASCII Break" that you mentioned? You can use the OUTCOMM command to send any binary data from 0 to 255. However, it is assumed that the data are transmitted using the NRZ format of 1 start bit, 8 data bit, 1 stop bit and no parity.

All our PLCs carry CE logo with declaration of Electromagnetic compatibility with the Euopean Union requirement.

However, all the PLCs do not require FCC or UL certification due to the low power nature of the product (UL Class 2 devices) and the way in which they are being used. You can however still use the PLC in equipment that are destined for UL listings.

I assume you are using the LCD display to create a menu structure. You will need to use a memory location (DM or A to Z) to keep track of where you are and then a custom function will display the correct text based on the pointer.

If you want to use 3 buttons to change set point, there is already an example in your "samples" folder called "SetTimerCtr_SV.PC5" which you can follow to learn to change any of the 3 timers or 3 counters in the PLC.

We haven't personally tested a cellular modem ourselves so we can't really recommend any particular brand. Have heard some users used the Siemen GSM modem with success but it cost a bomb. If you find something low cost and work well please let us know.

Yes, we already released a Windows version of TRiLOGI software - WinTRiLOGI version 3.5. It works with newer E10+ PLCs. However, due to the timing compatibility issues between old E10 CPU and the Windows (Windows is too slow to react to the E10's required response time) we could not make the Windows version of the software work with the old E10npn and E10-Relays.

Price of E10npn+ and E10-Rly+ still the same as the older E10npn and E10-Rly.
