They are using the Genius bus for communications. I'll do a little digging to see why they are using COMREQs. I have some logic from the program that I'll paste into here to show you exactly how they are doing it/attempted to pass data to the RX3i. << RUNG 31 >> | | +-----------------+ +--------------------+ EQ_ +- | | INT | | | | +------------+ +-----+ | PCKT#4 -+I1 Q +------------------+MOVE_+-------------------------------+MOVE_+---------------------<+> | | | | INT | | INT | | | | | | | | | CONST -+I2 | %R08756-+IN Q+-%R06069 MOD_HRT-+IN Q+-%R06079 | +00004 +----------------+ | LEN | | LEN | | |00023 | |00001 | | +-----------+ +------------+ | Program: LANTEST C:\LM90\LANTEST Block: _MAIN 05-01-07 15:52 GE FANUC SERIES 90-70 (v7.02) Page 12 | << RUNG 32 >> | | +-----------+ +<+>-------------+COMM_+- | | REQ | | | | | %R06050-+IN FT +- | | | | CONST -+SYSID | | 0002 | | | | | | CONST -+TASK | | 00000001 +------------+ | I don't know if any of this will help jog your memory or not.

Thanks Steve, that acutally makes alot of sense the only thing I am worried about is the 90-70 also communicates via COMMREQ to another 90-70 and a few other series6 PLCs (That's why we were trying COMMREQs in order to keep same communication styles). Would what you suggested affect the communications between the other PLCs? Also does the Rx3i bus controller have to be set up as SBA 21 or will any open SBA address work? Thanks again for all your assistance I'm getting a clearer picture than what I received from tech support!

Steve, I have a copy of the Logicmaster program (ladder logic) that is being used and it says GE FANUC SERIES 90-70 (v7.02). So I'm assuming its v7.02 of Logicmaster. I do not believe the "GENI-BASED" or "GENERIC I/O" choices in the 90-70 Bus Controller was tried (I was on the other end of the plant with the RX3i with someone else trying to send the COMMREQ from the 90-70. I believe the Genius bus configurations do match (as far as the Serial Bus Address being available on the bus and the Data Rate matches up at 153.6) but other than that I'm a novice at Genuis bus. I'll try and get an answer on the "GENI-BASED" and "GENERIC I/O" choices on the 90-70 bus controller tomorrow. Thanks for all your help thus far. Aaron

I've got a bit of a problem trying to add an RX3i to a Genuis bus network. The Genuis bus controller is based in an 90-70 using the old logicmaster software. I am trying to send data from the 90-70 into the R%01000 register range on the RX3i using a COMMREQ block. The problem with that is the old logicmaster program only has options to select a 90-70, 90-70 advanced, 90-30 and 90-30 advanced. Of course I tried every option and none of those were putting the data in the R%01000 address range on the RX3i. Has anyone else ran into this scenerio. Any advice is greatly appreciated. Thanks, Aaron

I have an Intellution IFIX application that I am wanting to manually start and stop the polling of some control logix PLCS through RSLinx Gateway. Basically the set up is to have a Start and Stop button in the Ifix application that when the START button is pressed RSLinx Gateway begins polling and collecting data from the control logix PLCs. THen when the STOP button is pressed in the Ifix app RSLinx stops polling the control logix PLCs. Does any one have any thoughts or ideas on how to do this? Thanks in advance!

I was wondering if anyone knew how to send data from Excel to an Omron PLC using CX-Server 2.1 I am trying to send the pc clock value to the PLC and store it in a register without having to get the memory card for the CQM1H-CPU51 that has the clock on it. Thanks

Thanks Jay. Looks like we posted at the same time :-p

I believe I figued out that the Control word for the serial ports are #0100 and #0200 for port A and port B respectively

I looked up the Serial Port Handling info and I understand that Operand 2 = Control Word which sets the port number and #1000 = Peripheral port. However I was looking for what the port number (#XXXX) is for Port 1 and Port 2 on the SCB41 Inner Board?

I am trying to set up simple communications between a DVT camera and a Linx 4800 printer back to a CQM1H-51 CPU using no protocol and I'm just running in circles as to how to do this. I'm trying to find out the control word for both the 232 port and the 485 port so I can test that I'm receiving my data using the RXD instruction. Thanks in advance for the help!
