Operating Instructions
2.9 Sequence for the Start-Up of the 1P 241
1)
Check for up–to–date software and hardware status.
1.1) Shielding of encoder lines (Shielding with potential (Mext) (e.g., by screw connecting the
metal housing of the connector on the 1P side).
1.2) Internal encoder supply (from 1P 241)
External encoder supply (at encoder)
1.3) Perform potential equalization with sufficient cross sections.
2) Setting the DIP switches on the basic module
Dip Switch: S1 (Module address = interrupt lines)
see sections 2.1 to 2.8
S2 (Group interrupt, peripheral byte O)
see sections 2.1 to 2.8
3) Configuring encoder supply voltage for incremental encoders on the 1P 241 basic
module

8) Setting up start-up organization blocks (OB20to OB22)
– Save scratchpad flags
– Parameterize
1P 241 with FB 156
– Delete interrupts with FB 157 (BEF = any)
– Reload scratchpad flags
– Consider time requirements according to section 8.3
