change "FB250&FB251" into "S7-Program."

Hi!

In "Onboard analog I/O of a 95U"
The input is calculated by "FB250" and the output is calculated by "FB251."
I want to change "FB250&FB251" into "S7-Program."

There is choice from "FC100" to "FC111" in "STEP7."
Which becomes optimum FC to transpose "FB250&FB251" to "S7-Program"?

Please Teach.......Thanks

Hi!

This time, I experience analog input and output for the first time in S7.
In S5-95U, analog input and output have been performed through "FB250&FB251."

Although "FC105&FC106" which Mr. "mer67" taught seems to be only FC which carries out scaling of the value in PLC

Which becomes FC which outputs and inputs analog value to PLC from an analog module?

I am sorry to be a fundamental question,
I am a beginner in S7.

Thanks

If it changes into "S7-Program" using "Converting S5 Files"
Although "FB250&FB251" is changed into arbitrary FCs of a number

In the appended PDF file (If I have you expand and see, it is visible to a fine character.)

The block of S5 was changed into FC number as follows.
FB250--->FC 0
FB251--->FC 1
PB 1--->FC 2
PB 2--->FC 3
PB 3--->FC 4
OB 1--->OB 1

"FC 0&FC 1" changed newly,
Does it function, if the value of "BG, KNKT" is united with "HW Config"?
Or is it necessary to newly prepare FC?

Thanks

Dear Melsec!
I have one project which used FB250. The system included 1 CPU S5-95U, 1 Module DI and 1 Module DO. CPU S5-95U has integrated analog Inputs. The program of system has FB250. Now I am converting from S5 to S7 and have the same problem. Do you have solved it? Please share for me.

Hello!!

In order to make understanding easy, I give an example to you.

"S 5-95" is updated to "S7-314C-2DP."

The program which is moving by "S5-95U"

The value of an onboard analog input is changed into BCD, and is displayed outside.

This S5 program is changed into S7 program using "Converting S5 Files."

A program after changing

OB1
Network 1
A I 32.0
= M 10.0

CALL FC 1
BG :=8
KNKT:=W#16#4
OGR :=9999
UGR :=0
EINZ:=M10.0
XA :=MW100
_FB :=M10.1
BU :=M10.1

L MW 100

CALL FC 82
DUAL:=MW100
SBCD:=M20.0
BCD2:=MB32
BCD1:=MW30

L MW 30
T QW 32

OB1 is to OB1.
FB250 is to FC1.
FB251 is to FC82.
　　It was changed automatically.

FC1 is the program not functioning.

Then, it changes for "FC105 SCALE CONVERT" in "TI-S7 Converting Blocks."

The value outputted from "FC105 SCALE CONVERT" is FLOATING_POINT.

It is necessary to change into making consistency have at DEC.

Of course, input and output of a signal are also changed in accordance with 314C.

The corrected program

OB1
Network 1
A I 124.0
// A I 32.0
= M 10.0

JCN X000
CALL FC 105
IN :=PIW752
HI_LIM :=9.999000e+003
LO_LIM :=0.000000e+000
BIPOLAR:=FALSE
RET_VAL:=MW150
OUT :=MD200

L MW 150
L 0
<>I
= M 10.1

L MD 200
TRUNC
T MD 204

L MW 206
T MW 100

X000: NOP 0

// CALL FC 1
// BG :=8
// KNKT:=W#16#4
// OGR :=9999
// UGR :=0
// EINZ:=M10.0
// XA :=MW100
// _FB :=M10.1
// BU :=M10.2

L MW 100

CALL FC 82
DUAL:=MW100
SBCD:=M20.0
BCD2:=MB32
BCD1:=MW30

L MW 30
T QW 124
// T QW 32

By doing in this way, it can be made S7 program which is compatible with S5 program.
