1) Communication error
When HMOP is not communicating correctly, "ERINF" becomes "1". So, the message on the display
unit of CNC can be displayed.
2) Power-on/off information
After HMOP and CNC once communicated, Power-on/off information PWR01 becomes "1". When the
HMOP is disconnected or the power supply is OFF, the signal becomes "0". By using this input
signal, PMC LADDER can detect whether the HMOP is connected or disconnected （The power is
turned on or off.） So, the message on the display unit of CNC can be displayed. There are 22 Power-
on/off information (PWR01 to PWR22), but please use PWR01.
Turning off the power supply could be detected by only PWR01 signal though there are 22 signals.
When "ERINF" is "1", Power-on/off information is not valid. Please judge the Power-on/off
information under the condition of ERINF is “0”.

Note）When the HMOP is disconnected or the power is off or communication alarm is
occurred, the input signals from the HMOP will be all “0”. The timing that the input
signals are “0” are not defined compared with the timing that ”ERINF” is ”1” and the
timing that ”PWR01” is “0” .
