Setting the
polarities of
the input
terminals
D1804
If users want to turn an input terminal into a Form A contact, they have to set the bit
corresponding to the input terminal to ON. If the users want to turn an input terminal
into a Form B contact, they have to set the bit corresponding to the input terminal to
OFF.

Reading the
states of the
input terminals
D1805
If a bit in D1805 is ON, the input terminal corresponding to the bit receives a signal. If a
bit in D1805 is OFF, the input terminal corresponding to the bit does not receive a
signal.

Setting a filter
1. Users can set the hardware filter for the input ter
minals START, STOP, DOG,
LSN, LSP, and PG by means of D1806.

O100 error
1. If an error occurs
in O100, M1953 will be ON, the error code corresponding to the
error will be stored in D1802, and the step address at which the error occurs will
be stored in D1803.
