The parameter specified in these parameters by the user is the source parameter when corresponding digital I/O line is set as an output or destination
parameter when corresponding digital I/O line is set as an input. A total of 8 source or destination parameters can be defined. Pr x.21 to Pr x.28
corresponds to bits 0 to 7 (DIO1 to DIO8) respectively.
When the output select parameter for an I/O line is set to On, the I/O is set up as an output as follows:
The drive parameter defined by this parameter is the direction register for the fast update method. Setting the relevant bit to 1 within the direction
register parameter will select the corresponding I/O line to function as an output. If this parameter is set to 0.00 or a non existent parameter then all
I/O lines are defined as inputs for the fast update method. The direction register parameter range may not be large enough to allow all I/O lines to be
controlled. Any bits that cannot be controlled are assumed to be zero and the corresponding I/O lines are defined as inputs for the fast update
method.
The drive parameter defined by this parameter is the read register for the fast update method. When an I/O line is set up as an input for the fast
update method the corresponding bit in the read register shows the state of the input. Bits that correspond to I/O lines that are set as outputs in the
direction register or in the direction registers for the standard update method show the state of the output I/O line. If this parameter is set to 0.00 or a
non existent parameter then no read register is defined. The read register parameter range may not be large enough to allow the state of all I/O lines
to be shown; in this case the value containing the I/O status for all 32 I/O lines will be limited to the read register parameter range before being written
to the read register parameter.
