Parameters of the IP 265 User Program

Parameters can be exchanged between CPU user program and IP 265 user program via the PIQ
and the PII:
• The CPU user program can write input parameters (6 bytes) into the PIQ where they are read by
the IP 265.
• The IP 265 can provide IP 265 program results in the form of output parameters (6 bytes) which
are read by the CPU user program in the PII and evaluated.
For IP 265 and CPU program generation, the parameters must be defined accordingly and supplied
with parameter data. In Section 13 "Sample Applications and Programming Aids", you will find
examples of this.
Input parameters
Input parameters guarantee the supply of the IP 265 user program by the CPU user program.
Note
The input parameters are only processed by the IP 265 if the RUN bit is set in the
control word.
The following input parameters can appear in the input bar of the control system flowchart (IP 265
user program):

Input Parameters
Count, time value
Bit input parameter
The counters and timers in the IP 265 can be supplied with constants by the CPU user program.
However, it is not possible to work with the SIMATIC S5 constants for timers (KT) and counters
(KC). Constant count and time values can only be transmitted in BCD code from the CPU to the
IP 265.
