You can go here http://globalcare.gefanuc.com/ and search "CAD 'part number'" You will need your GE SSO, or get one.

Thanks, you are right. Once you master the Array function blocks you can make your PLC do anything but sing. This thing can be used to handle bits, bytes, words or double integers. Along with the Array look-up function blocks it is very flexable.

Yes, UserDefinedFunctionBlocks, the RX3i has it all, including the ability to store descriptions and with its Pentium PIII and 10Meg of RAM there is generally room to include your CAD files in the upload. Look it up on the net, you may be impressed. www.gefanuc.comI did not mean to bash anyone or any product, but I wanted to correct a miss-conception. All PLC/PAC manufacturers have thier strong points and weak points. That is why I think that companies should not limit thier controlls to one supplier. By doing this they may "get the best available by thier supplier, but they may not have the best for thier project."

Obvously you have not looked into the RX3i, you're right it does not compete, it is way ahead of CLX.

These two files will help, the pcm_rtu file has an example.pcm_rtu.zippcmtips.zip

You may number them in any way you like, just do not go over the max and do not give two nodes the same number.

There are couple of ways that I know of, all will cost you, some in money others in time. 1. You can purchase the 'Change Management' software module from GE Fanuc. 2. On the install CD you will find a program called 'CSDiff.zip' under the 'Manager Tools' directory, install this and READ/Understand all documentation. With this you can compare the 'text' version of a Block (yes one block at a time). To get the text version: open a block, Ctrl-A, Ctrl-C, open "Notepad.exe' and Ctrl-V. BTW you can develop logic in notepad or Excel or any program that you can copy ASCII text from by typing the proper sytax. 3. Borrow or purchase a duplicate system, without I/Q will work, Load one program into the CPU and the other in Proficy ME go 'Online' then select 'Target' > 'Compare'

I am not sure what you mean? Automatic Aliasing? Please explane.

This works ONLY if you are using the PAC PLC ( RX3i or RX7i). Please accept my appologies if GE Fanuc has decieved you in any way.

For future reference, where/what did you find a bad connection? This information may help someone else.

The most likely problem is a data length problem or bad .gds files. Did you add any system or diagnostic bytes needed by the output modules? Just out of curiosity are you auto configuring the VersaMax I/Q blocks?

Try to open it from the post, it works for me.

You can find this and more at the GE Fanuc Global Care Web site. This is what you are asking for. MomentaryPB.zip There are many more here: http://globalcare.gefanuc.com/default.asp

I do not have a lot of these but we have not seen any failures yet. This CPU has two serial ports plus ethernet that can be used for Modbus communications, which are you using and how? For short distances the RS-232 can work but then all devices need to be powerd from the same source, or properly isolated. The RS-485 will be more noise immune but you still should isolate the comm lines if the devices are powerd from different sources.

It can be done. The 14pt has 1 RS-232 port. The 23pt and 28pt VersaMax Micros each have 1 RS-232 and 1 RS-485 port. The 64pt has 1 RS-232 and a second optional port which can be RS-232, RS-485, USB or Ethernet. If your barcode reader supports one of these and one of the supported protocols you are all set. The protocols are ASCII, SNP, Modbus RTU (not all ports support all protocols) IMO it is easier with the PCM or bringing this into a QuickPanel View with a script.

Yes, By entering the correct number in the "Time Base" configuration paramater... The number of milliseconds for which the counter counts input pulses and returns the number of counts detected during that time to a 16-bit register. If the number of counts detected is greater than 65535, the 16-bit register overflows. Select a timebase small enough to prevent overflow. Valid range: 0 through 65535. Default: 1000. Or: For each counter, the timebase represents a span of time which can be used to measure the rate of counting. For example, the program may be required to monitor the number of count pulses which are occurring every 30 seconds. The Data Register that holds the results will be the 2nd, 3rd, 4th, or 5th of the %AI assigned to the HSC module. This is dependant on the type of counter configured, A, B, or C. More detail can be found in GFK-0293 HSC manual. HTH

You and Steve are probably both right. It is most likely that your newer notebook's RS-232 UART circuitry has trouble detecting the voltage from the RS-485 UART's electronics of the PLC. I have run into a few like this that some times do not work with the "cheater" cable.

Or: See attachment but it is not supported by GE Fanuc.

These symptoms are generally caused by 'noise' and in some plants shut-down noise can be extreme. But... If you can pinpoint the device and version that is giving you the problems and that equipment is still available, and it can be duplicated by GE Fanuc it will get fixed. If the affected units are identifiable verify the version and up/down grade to a version that is not affected. If the affected units are random it is most likely an electrical noise problem. If it is not tolerable it can be fixed, the real question is how long and how much? As for the waiver, you can get around this by ordering the pre "plus" version, check with your friendly distributor for a suffix to add to the IC693CPU374-DJMP part number.

You would need to do the same with the CPU374 to get two networks(NICs) as the CPU374 is a 2 port switch (1 IP) not two NICs. Also neither the CPU364 or CPU374 do Modbus TCP/IP yet. You can get a CPU374 by talking to your distributor and asking for the 'waiver' that currently needs to be signed to get a CPU374 delivered. The current problem does not affect the operation of the unit, the problem is that once-in-a-while it will not powerup in 'Run' mode you need to cycle power one more time. Anyone who signs the waiver will be updated as soon as the fix is available. Or, you can get around this by ordering the pre "plus" version, check with your friendly distributor for a suffix to add to the IC693CPU374-???? part number.

Neither the CPU364, 374 nor the new 374 support Modbus TCP/IP right now. The CPU374 (new enhanced version) is scheduled to have it added in a future release. You can use the CMM321 as Steve indicated, we have done this with the Banner Vision Sensor so it should work with Cognex. It should work as well with Devicenet, but there are advantages to having everything on the same wire.

There is not an analog module in Genius or the 90-70 with ALG260 in the part number, it would be VERY helpfull to give complete information when asking a question like this. I will guess that you actually have VersaMax I/O. I suggesst that you: A. configure the NIU again, either by performing another Auto-config procedure or double checking your manual configuration and downloading it again. B. verify that all wiring is correct C. verify that the jumpers on the module are the same as the configuration, if they do not match the config will not be equal (do this first)
