CompactLogix 1769-L16ER
Studio 5000 30.14
I/O modules: 1734-IE2V, 1734-OE2V, 1734-IB8, 1734-IB8, 1734-OW4
Machine was working fine for long time. Yesterday Maintenance had problem with login out so they power off machine and power it back. After this point there is problem with I/O modules. On compact logix I/O led flashes green.
On Modules:
Modules status - Green - additionally tested and power seems to flow correctly.
Modules Network - off
Hardware was changed but still the same problem. RCPI was increased to 200ms and still nothing. PLC have problem to see modules. RSLinx can't find modules.
any suggestions ?
