Expansion of a PCS 7 project
When you expand a PCS 7 project and load it in the CPU, a check is made to determine
whether the project can run in the CPU with the current number of POs. If this is not the
case, you have two options to expand the number of POs:
● By replacing the system expansion card
● Online with the corresponding number of CPU 410 expansion packs
Expanding the number of POs by replacing the SEC
To replace the SEC, you must remove the CPU, which also results in the deletion of the user
program on the CPU. You must replace both SECs for redundant operation. The new SECs
must have the same number of POs.
Expanding the number of POs without replacing the SEC
You can expand the number of POs in four steps without replacing the SEC.
Step 1: Order the number CPU 410 expansion packs you need using the regular ordering
process. You can order expansions for 100 POs and 500 POs.
Step 2: Assign the CPU 410 expansion packs to the respective CPU.
Step 3: Activate the expansion.
Step 4: Transfer the release of the expansion to the CPU.
A detailed description of the procedure is available in the
PCS 7 process control system,
Service support and diagnostics (V8.1)
manual.
Note
This function can only be used to expand
the number of POs. You cannot the reduce the
number of POs without replacing the SEC.
