Clamp the cable shield with the cable clamp on the grounding plate of
the cabinet on the built–in I/O side.
When the cable used is not a shield cable, it must be used only within
(8)For details of the signal specifications, see Section 6.3.
(9)Ensure that the cable is securely plugged into the unit. Otherwise,
problems such as DI/DO signal transfer errors may occur.
(10)The DO points of this built–in I/O module are designed to be turned
off when a system alarm occurs in the Power Mate and when the Power
Mate power is switched off.
(11) The DO driver of the built–in I/O is capable of detecting an overcurrent
and measuring its own temperature. If an accident, such as connecting
the cable to ground, causes an abnormal increase in the load current
or in the driver temperature, a protection circuit, which is provided for
each DO driver (1 byte), is activated which keeps the DO signal for the
relevant 1 byte in the OFF state until the cause of the problem is
eliminated. Even if this occurs, the Power Mate continues operating.
The DI address (F248) identifies which DO driver has detected an
alarm. The following table shows the correspondence between the
PMC address (F248) bits and the DO addresses. Bit value “1”
indicates that the corresponding DO driver has detected an alarm. If
a DO error occurs, the F248 area can be checked on the DGN screen
of the Power Mate. Performing alarm processing for F248 in advance
by using Ladder ensures safety and assists in fault investigation and
