SVCREQ #14: Clear Fault Tables

Use SVCREQ function #14 in order to clear either the PLC fault table or the I/O fault table. The SVCREQ output is set ON unless some number other than 0 or 1 is entered as the requested operation (see below).

For this function, the parameter block has a length of 1 word. It is an input parameter block only.

0 = clear PLC fault table.

1 = clear I/O fault table.

address

Example:

In the following example, when input %I0346 is on and input %I0349 is on, the PLC fault table is cleared. When input %I0347 is on and input %I0349 is on, the I/O fault table is cleared. When input %I0348 is on and input %I0349 is on, both are cleared.

The parameter block for the PLC fault table is located at %R0500; for the I/O fault table the parameter block is located at %R0550. Both parameter blocks are set up elsewhere in the program.
