Hi, I have the following configuration where 4 PLC panels, with each having a Q12PH CPU and QJ71E71-100 module. All these QJ71E71-100 are connected to a HUB using straight cable. From the HUB one connection is going to an I-Fix SCADA which is already communicating with all 4 PLCs using MC protocol. I want to send data from 3 of this PLCs to the 4th PLC in the same network using fixed buffer communication. Can anyone provide a sample program for the same. Send and Receive side. I am using GX Works 2 for programming. Your help is very much appreciated.
Hey everyone, I have a CJ1M PLC with a CJ1W-SCU21-V1 serial card. It is unit 6 and I am using port 1. I have bit 1659.06 ((1500 + 25 * Unit #) +9, bit 6) as "characters in buffer" but it never comes on (data is being received through the port successfully). It is on No-Protocol mode. Does anyone have any ideas as to how I can detect data in the buffer?
I have an FX3u16MR attached to two FX3u4AD units (right mounted). I am running the first two channels of the eight in 12 bit mode, the next two channels in 16 bit mode, the next two channels in 12 bit mode again and the last two channels are idling. All inputs are configured as 4-20mA. Working with the first channel only for now, what I am finding is that I have to load the gains twice for them to take. It points to a timing issue in the code that I am running in the plc. It just seems to have started happening though. Admittedly I am recoding so the ADC calibrates from a HMI rather than from a PC trigger which is what I had before. But I have just paralleled up the M register that invokes it. I am working through the code as I speak. If anyone has any idea's i would love to hear from you. I know this bit of kit fairly well I am just missing something here and it is bugging me. A problem shared and all that. Thanks in advance.
