QUESTION:
With OP7/OP17 can I execute CPU functions without having to use a STEP7 programming package?
ANSWER:
There are some functions that you can use without having to use a STEP7 programming package. The following functions are implemented:
- S7 operating mode change
STOP: puts a CPU S7-300 into the STOP operating mode.
START: puts a CPU S7-300 into the RUN operating mode
- S7 data backup
RAM-TO-ROM: copies the current main memory contents of an S7-300 into the memory card or the built-in FEPROM.
Through this function you can do a non-volatile save of the changed machine parameters at start-up.
Procedure in ProTool V4.0 and higher:
- S7 operating mode change:
Assign the function key with the corresponding function as follows:
1. Open the "Functions" tab
2. Under the "Object selection" box select the "NC/Positioning module" item.
3. Here you will find the function "S7 Operating modes"
4. Add this function with the "START" or "STOP" parameter via "Add to function key".
S7 data backup:
Assign the function key with the corresponding function as follows:
1. Open the "Functions" tab
2. Under the "Object selection" box select the "NC/Positioning module" item.
3. Here you will find the function "S7 Data backup"
4. Add this function "RAM-to-ROM" via "Add to function key".
WARNING:
With this function you must first switch the CPU to STOP.
