IO FUNCTION BITS
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.
The control1 register contains 16 level sensitive input signals. This register has 5
control sources which are combined together.
control1_inputs come from the digital inputs as set with the ‘INx functions’.
control1_internal are internally generated signals (e.g. the START/STOP keys).
control1C and control1G are registers accessible via communications and are for
remote control of the instrument.
control1_input_aux come from auxiliary IO
The 4 registers are or’ed together, so for example a 1 on bit 2 of any of the 4
sources will set the run bit. Any control1 register with bit 1 set (stop) will override
and cause a stop.
To invert signal, use negative value.
e.g. for NOT run, use -2.
† IN0 is pulse input, other inputs are no function.
‡ Only OUT0 & OUT1 maybe set to pulse output. Other outputs are no function.
Ϯ can be set and reset with macros and the setting IO Control (Q25420)
* retained while power is off
