Beijer Electronics (formerly QSI Corporation)

We purchased a G70 unit to test with our Opto22 LCM4 and Factory Floor setup. Since the ioManager does not work with this older hardware, is there some other way to program this unit to act as our HMI?



There may be a possibility for us to upgrade to the PAC-S next year but currently we can not reduce capacity during this time of the year in order to test out a line.

Thanks!

I know that the G70 has drivers out of the box to talk to the memory map controllers (Ethernet io, Ultimate io & their new one (PAC?)).



It can also communicate directly with strategy variables on the Ultimate io and the PAC.



As a last resort, the G70 can communicate via Modbus to some of their controllers.



Unfortunately I am not particularly familiar with the LCM4 so I cannot comment on how to setup communication with that device. Opto 22 technical support may be better able to guide you there.

The only problem with all of these drivers is that they communicate via Ethernet. We are using the serial B3000 brains and LCM4 serial communications. Not even the first version of ioManager looks at the serial versions but all are based on the Ethernet communication.



We are going to experiment with developing a serial driver to look at the memory map on the B3000 brains through Factory Floor. Once we have the memory locations, we should be able to program these into the G70 with ease. The biggest problem is the timing of the change. We are down several HMI's and the unit we used before is now obsolete. Currently we are using laptops and PC's to handle the change.



Any ideas if there is a way to perform a mem map function from the G70? If we could connect the two and have the function already available, it would make life easier at this time.

Thanks for your quick response. We already talked to Opto and they said they are not compatible. We also tend to think larger and have no problem with the impossible.

Ah, now I see. We don't have any out of the box drivers that will talk to an Opto device serially. Unless the LCM4 or B3000 can act as a Modbus slave (I know certain Opto devices are capable of behaving that way.







The G70 does not directly support being a memory map "host" (i.e. there are not memory map locations on it that can be read or written via the IEEE1394 protocol). The G70 can be a memory map "client" -- which is what it does when it talks with the Ethernet io. The memory map drivers unfortunately only support ethernet communication and we are, unfortunately, not able to release the source code to those drivers for you to modify to be serial based (which wouldn't be too difficult).



There are probably several possible solutions to your problem. The fact that the G70 itself is fully programmable means that it is absolutely possible to program it to speak in a way that your LCM4 can understand. The only question is how much work it will be.
