Fp0 Program Compatibility - Panasonic FP0R User Manual

Overview

2.5 FP0 Program Compatibility

Programs from the existing FP0 can only be used on the FP0R, if they:
1. conform to FP0R specifications, or
2. are executed in FP0 compatibility mode
Using programs that conform to FP0R specifications
This allows you to make maximum use of FP0R performance and functions. However, the
following modifications to the FP0 program must be made before downloading the program to
the PLC:
1. Change the PLC type from FP0 to FP0R using the programming software.
2. Since the system registers will be initialized when the PLC type is changed,
reconfigure the system registers if necessary.
3. Modify the programs according to the FP0R specifications if necessary.
Executing programs in FP0 compatibility mode
The FP0 compatibility mode allows you to use existing FP0 programs as they stand. With a
few exceptions, the same specifications apply as for the FP0.
To enter the FP0 compatibility mode, use your programming tool to download the FP0
program. A confirmation message will appear, and the mode will automatically change to the
FP0 compatibility mode. The FP0 program may either have been uploaded from an FP0 or it
may have been created on an FP0R in FP0 mode (PLC type is FP0).
The FP0 compatibility mode is supported by FPWIN Pro V6.10 or higher, and FPWIN GR
V2.80 or higher.
NOTE
Due to the FP0R's higher operation speed, the scan time in FP0 compatibility
mode may be shorter than the original FP0 scan time. If you require a scan time
close to the original conditions, set a constant scan time in the system
registers or add a dummy program, e.g. a loop operation, to increase the scan
time.
For an FP0 program to be able to run in FP0 compatibility mode, the PLC types (C10, C14,
C16, C32, and T32) must match exactly. FP0 compatibility mode is not available for the F32
type FP0R.
In most respects, the FP0 programs do not need to be modified to be executable in FP0
compatibility mode. Please note, however, the following differences between the
specifications, and change the programs as necessary:
1. P13_EPWT, EEPROM write instruction
The execution times for this instruction will vary, depending on the number of write
blocks.
