ERINF------ -
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” .
