This is a read PLC
App. PlcInOut. DeviceReadWords (device_name, device_number);
To name and number, will return a ushort array, the array should be, the state of the input and output.
As to the calling failure
The background color of the lblPLCInterface red
The test, a line of words showed
And will PLCconnect closed
And returns an error

CodePudding user response:

Agree with above, in addition to "and returns an error", should be if the call fails, throw an abnormal communication

CodePudding user response:

Annotation is not tell you yet, right to be obtained directly back, throw an exception error,
