Step5 FB25

[romaitor]

Hello,
I'm trying to migrate an ald S5 PLC(S5-95U). In the code there is a call to a FB25. I don't know anything about this block and I need information of how it works. In the picture I see "P71200-S 5015-A-1" but if I read than document, the FB it talk about has more parameters than th FB you can see in the picture attached.
Hope someone help me.
Thanks.

These blocks are for floating point operations.
I cannot find a manual, but if you have STEP7 V5, then there are S5-to-S7 conversion blocks for which you can have help.
Open Standard library .. S5-S7 Conversion blocks, and finde the header name, i.e. GP_FPGP.
For this block the online help says:

Parameter Data Type Memory Type Description

Z_12 WORD I, Q, M, L, D, const. High word of integer
Z_11 WORD I, Q, M, L, D, const. Low word of integer
Z_22 WORD I, Q, M, L, D High word of floating point number
Z_21 WORD I, Q, M, L, D Low word of floating point number

Description of instruction:
The GP_FPGP instruction (FC61) converts a fixed number (integer) to a floating point number.
