IOx
In most cases, IO Function bits are set and reset by the controller or the digital input
signals.
MODBUS
The registers control1, control2, control3, status1, status2, status3, IOx, faults,
control4 and IOx2 can all be read over modbus.
The registers control2, control3, control1C and control1G can be written to over
modbus.
Bits marked Ϯ can also be set by writing their bit number to the IO Control register
(address 8038). Writing the negative value of the number will reset the bit. For
example writing -14 to 8038 will reset ‘user bit 1’. (write 14 to set)
MACROS
IO Function bits 1 to 187 can be set & reset using the SET_BIT, CLEAR_BIT and
TOGGLE_BIT instructions.
The IF instruction can test bits 1 to 150.
This register hold the state of inputs IN1 to IN8 and outputs OUT1 to OUT8.
The status of IN0, IN9, OUT0 and OUT9 are in the status3 register
