Configure inputs for S5-115U
Hi Experts,
I've started a small hobby-project and for this I'm using a S5-115U. I'm using a programming software called PG-2000 (not a "real" Siemens product but it seems to work). I'm able to program the PLC without any problems, so far everything is fine. Next step, I want to connect a few inputs to the PLC. I've a card with 32 * 24V inputs. I've connected 24 volts and the LEDS are reacting as expected. However, I imagine that I need to configure the hardware (what kind of cards that are connected to the rack). I can not find a setting for this in the software. Or do I need to program this? All suggestions are very welcome! Thanks! //Supporter |

S5-95U, S5-100U and S5-115U series didnt need much hardware setup. There was something in DB1, but most times you didnt need to modify it. From S5-135U and up you had to set dipswitches on the modules, but that is another story.
On S5-115U the addresses of the i/o is determined by the location in the rack. It is in the manual: http://support.automation.siemens.co...iew/en/1085937

The S5-115 I/O was hard coded in the PLC memory.Each slot after the CPU has 32 bits of I/O which can be either Ins (I) or Outs (Q). If a 32 bit I/O is inserted all 32 bits available. If a 16 bit card is inserted only first 16 bits are available first slot after CPU is addressed as: I0 ( bits 0 - 7 ) or Q0 I1 ( bits 0 - 7 ) or Q1 I2 ( bits 0 - 7 ) or Q2 I3 ( bits 0 - 7 ) or Q3 next card : I4 ( bits 0 - 7 ) or Q4 I5 ( bits 0 - 7 ) or Q5 I6 ( bits 0 - 7 ) or Q6 I7 ( bits 0 - 7 ) or Q7 next card : I8 ( bits 0 - 7 ) or Q8 I9 ( bits 0 - 7 ) or Q9 I10( bits 0 - 7 ) or Q10 I11( bits 0 - 7 ) or Q11 ....
