Possibilities of Access
There are the following possibilities for using the digital I/Os on the
optional module MD1:
• direct access via master communication by the master (e.g. PLC)
• configuration of I/Os to any (see S-0-0398 and S-0-0399) drive
parameter and bit
• direct access to I/Os via integrated PLC
• configuration of digital inputs for safety technology on MD1
Direct Access to Digital I/Os of Optional Module MD1 via
Master Communication
In order to transmit data to the digital I/Os directly via the master
communication, the following steps are required:
• configuration of:
• [P-0-0681] = "S-0-0000"
• [P-0-0682] = "S-0-0000"
The parameters P-0-0081 and P-0-0082 can then be used as mere
"data containers" for exchanging data between drive and master.
• configuration of P-0-0081 and P-0-0082 in the cyclic data
• including parameter P-0-0081 in the group of cyclic command values
(SERCOS: S-0-0024, field bus: P-0-4081)
• including parameter P-0-0082 in the group of cyclic actual values
(SERCOS: S-0-0016, field bus: P-0-4080)
The figure below illustrates the access to the digital I/Os of the optional
module MD1 via the master communication (SERCOS in this case).
