Connection problem TSX Premium ethernet
Geir replied to Geir's topic in Modicon / Telemecanique / Schneider Electric
The problem was the missing expansion rack, once I put the termination plug in the spare X-bus connector on the main rack the ETY port entered RUN mode and started communicating :) Never imagined it would be so vulnerable to an elementary fault :( Geir -
Connection problem TSX Premium ethernet
Geir posted a topic in Modicon / Telemecanique / Schneider Electric
Hi, our school got a box of surplus M340 and TSX Premium from a local company, I don't have any detailed info on any of them. When I connect the TSX Premium to my local network, it gets an IP address, and I can ping it, but it will not connect to UnityPro. Error: Invalid address or busy PLC. Looking at the indicators there are a few error lamps, on the CPU TER is lit and ERR, on the Ethernet part (built in ethernet) STS is lit ERR flashing and RX flashing briefly. Also all the IO modules have ERR lit. Is this something that can be sorted with the TXP/IP connection, or will I have to get the adapter for the terminal input. On the same network the M340 seems to be connecting just fine. Until now, I have very little experience with these PLCs, we mostly use Omron equipment at our school. Any input appreciated.... Geir -
Could it be that you are missing some expansion instructions? Geir

The label says TSXP573634M Process uny 573x4 ETH. That should be a Unity pro cpu, I think. It was originally installed 2005ish. I have also tried one of the other racks and that behaves exactly the same. We also got some expansion racks, that are not connected now, could that cause this kind of problem? Geir -
There is probably some scaling involved, first you need to find the input range of the PIDAT itself. Look for a MOV that puts a HEX number like #1494 in the Setpoint + 6 address. IE if the setpoint is at address D3101, the range control parameter is in D3106. the second digit (from left) is the input range/resolution. 0 is 8 bits, 8 is 16 bits. 4 is a common value, that gives 12 bits resolution and a range of 0 to 4096. A setpoint of 50% would then be 2048. Geir

[Tech and Application Notes] - Guide for replacement from CPM2A to CP1L
Geir posted a topic in Download Comments
File Name: Guide for replacement from CPM2A to CP1L File Submitter: Geir File Submitted: 27 Aug 2013 File Category: Tech and Application Notes This guide describes the procedures and cautions for the replacement from CPM2A to CP1L. Please make sure to check the operation sufficiently before starting actual operation with CP1L. Click here to download this file -

In Europe you can register your software here: http://softwaredownload.europe.omron.com/europe/www/OmronIndustrial.nsf?login&redirectto=/europe/www/OmronIndustrial.nsf/WebApp/softwaredownloadarea and download new versions of your software in CD or DVD image format. (Within the main version number). Geir

The display is optional, but this is from the tech info, does not say how to fix it thou :( If the error is not obvious, I usually start troubleshooting by resetting to factory before making a fresh configuration. ➄ Device status (markers) on HMI display 1 = Hardware problem (any hardware problem making the device unable to provide a correct measurement (communication, memory problem…) 2 = No Reference Pulse 3 = Low Voltage or Measurement Old 4 = Level Lost Note: The current output will be set to 3.6 mA whenever the AKS 4100/4100 detects an error like: "Level lost", "Overfill error" or "Reference pulse lost".

Error output is when the sensor electronics detect a fault. Could be anything from out of range to sensor breakdown. Are there any error codes on the transmitter display? Geir

Upload from CP1H - Download to CP1L using CX programmer v9
Geir replied to ville's topic in CX-Programmer
Hi, these two PLS's are slightly different, the CP1H has sinking transistor outputs, while the CP1L has relay outputs. I'd check if the wiring is correct for the outputs. If the LEDs for the outputs are lit and nothing happens, it's probably a wiring problem. Geir -
Hi, anybody know of a supplier that will sell a couple of the HONDA MR34FG plugs? All the dealers I have found on the net have a minimum order policy :( My local Omron guy said he would look for one, but I haven't heard from him since... Geir

Having looked closer at this problem, I found that FWRIT saves everything as ASCII when using the .CSV format, including any inserted CRs in the data :( Haven't tried to save as binary though, it might work there. A possible workaround could be to insert a unique code in position 47 of each record, and then replace it with linefeeds in WORD before importing it into EXCEL. Geir
-
What about putting a HEX "D" (CR) in cell 47 before using FWRIT? Geir

Haven't tried it myself, but I suppose something likethisshould work, but the BCD version has limited resolution, the CP1 series seems to lack a gray decode instruction, and there won't be many inputs left on a "small" CP1E. Another option might be an encoder with 4-20mA analog output? Geir

Here is the manual http://downloads.industrial.omron.no/IAB/Products/Automation%20Systems/PLCs/Compact%20PLC%20Series/CP1H/CJ1%20Analog%20IO%20and%20Control%20Units/W345/W345-E1-11%2BCS-CJ-Series%2BOperManual.pdf and a section for configuring MAD 42, that is both In and out, but combined with the manual you should be able to work it out. It is also possible to confugure the module in the unit setup in the IO-table, but I prefer to do it this way. Geir Init_MAD eng.zip

Can't he use the trialversion? Geir

If it is a fairly new CPU it should not be a problem, but if it is an older unit it might not handle function blocks. On the side of the CPU, there is a label containing the CPU type numbers and various info. One entry should read "Ver. 3" or "Ver 4". Ver 2 or earlier did not have the FB functionality. Geir

Seems to compile OK on my PC running CX-programmer v 9.35. A few duplicated output warnings, but nothing fatal. One thing that comes to mind: is your other PLC unit ver. 3 or 4? Geir

The current version on the CxOne v.4 disk is 4.84, I think....

Hi, you need to check out the APR instruction, somewhere in this thread there is an example program. Geir

The DA041normally has a range of 0-4000 that would fit in 12bits (4096) Geir

Just MOV it from D43 to 20xx (the address of the DA module) Geir

Do you need to control temperature below zero? If not, I think the easiest thing to do would be to prevent the input to the PID from going negative (the PID takes an unsigned input) and set up the PID as 13bit in. The input should then be scaled to #1FFF max. If you only need a temperature range of 400 degC, you could set up the PID as 12 bit in without scaling. Geir
