Hi all, I have seen bits and pieces of information on the forum concerning my project but nothing really tying it all together. I am trying to use a Siemens S7-1200 CPU to drive a series of presses. The current PLC in place used an EA7-S6M touchscreen HMI to interface. I would like to reuse this touchscreen, but there is limited amounts of information on both sides of the fence. (I unfortunately did not budget for a new touch screen assuming I could figure it out)
I have seen some users suggest simply using the S7-300 protocol on the touchscreen which is all well and good, I was able to do so. But I still cannot get the two devices to communicate to each other. I have a feeling that I am not setting the proper parameters on the HMI or that I am not telling the CPU to look for the HMI on the network.
