Dear List, I am setting up an FBM232 using Modbus TCP. The ECB200 and ECB201 blocks are both showing good in system manager and all good green in FoxView. As soon as I build an IIN or BIN block to try to read from the device my ECB201 block fails and reads: DVC FAIL (red) OFF SCAN (grey) DCI READY (cyan) DVC ENABLD (cyan) DVC FAIL (cyan) To get back online I have to delete the IIN/BIN block and disable then re-enable communication on the ECB201. I've set up the ECBs the same way I have for other working ones but the device I'm talking to is different. Any suggestions as to what could be wrong? How can I determine if the problem is on the Foxboro end or the slave device?
