If the processor board, the PLC and graphics board, the CLP boards or EPROMs are to be exchanged, a MOS<br />
protection is definitely required, as otherwise MOS components on the boards or EPROMs may be destroyed.<br />
Note:<br />
Avoid any unprotected handling or contact of the boards or EPROMs with statically charged objects<br />
(packaging material, storage etc.).<br />

19.13 Software Compatibility<br />
Potential compensating line<br />
with protective resisitor<br />
mat lays on the machine table<br />
Exchange units (complete logic unit) are generally supplied with the latest software version. Exchange boards<br />
however, are always supplied without software and without software protection module.<br />
For this reason, the EPROMs and the software enable module of the defective board must be inserted into<br />
the exchange board at site (see sec. 19.9). Before sending us exchange boards for repair, always remove the<br />
EPROMs and the software enable module.
