Points to note:
195.For executing this instruction, scan time must be longer than 10ms. If scan time is shorter than 10ms, please fix the scan time at 10ms.
196.If the output points of PLC is transistor output, please apply proper
197.Operand n is used for setting up the polarity of the transistor output and the number of sets of the
198.The output point must be a transistor module of NPN output type with open collector outputs. The output has to connect to a
