Controller Digital IO error

Case description: This section describes possible faults and suggested actions for each fault when Controller Digital IO error.
Result: There is delay or no respond on the signal output in the IPC.
Possible reason: The following are possible symptoms of IPC that cannot be start up:

1.DO’s external device, whose current value is higher than 100mA, causing the IO circuit to burn out

2.The leakage current between the circuits of the IPC IO connected to the external device

The maximum drive current per channel is 300mA for TM5A/TMAA.  If the load exceeds maximum drive current, a relay should be used to drive it.
