Hello Experts, We have TDC system in our Hot Strip Mill factory. Also there is a Psystemdevice to measure the width of the strip. These two system communicating with each other by industrial ethernet network. In the CFC software, CRV block provide the communication. Last a few days we have problem with the communication of those two system. YEV status of CRV block is 16#0005 (No data received). YTS status of CRV block is 16#6003. But these two status values always changing with 16#0000.I mean, the status values 16#0005 and 16#6003 are not constantly waiting there. In the YEV block Life Counterrunning and seems to be normal. And B_WARNING outputbit is flashing with 1 and 0. Once a 15 minute approximately, B_COM_ERROR bit also is getting 1 for a few seconds. If one of the B_WARNING and B_COM_ERROR is 1, B_COM_OKoutput is getting 0. The CRV block is in T1 Cyclic Task and the the sampling time of this cyclic task is 4.0 ms. Do youhave any idea to fix this communication problem? The related CFC chart is attached. Thanks a lot for your help in advance. AttachmentIT_PEI_WG_1 -- COMFU101-RC-52_I.pdf (481 Downloads) |
