KelKoon is on to something.... Go to your "Hardware" config and double click on the CPU. Under the "Communication" tab it will be defaulted to 1 OP and 1 PG connnection. Change both to 2 and you should be good. Make SURE you SAVE AND COMPILE (5th icon from the left) your hardware. Then, DOWNLOAD to the CPU. You may be running out of communication resources. Everything is fine, until BOTH OPs are trying to read or write to the PLC and the same time.
