When converted to S7 and consistency checked in S7 found following error. Parameter BG,P_Q,KNKT, OGR, UGR, EINZ, XA, _FB, BU, TBITdoes not belong to called Block. Converted S7 program: FUNCTION FC 143 : VOID VAR_TEMP lok_kcpar : array [0..1] of word; END_VAR BEGIN NETWORK OPN DB 80; NETWORK L 'P '; T lok_kcpar [0]; CALL FC 1050 ( BG := 128 , P_Q := lok_kcpar [0] , KNKT := B#(0,3) , OGR := +0.1600000E+02 , UGR := +0.0000000E+00 , EINZ := M 0.0 , XA := DBD 20 , _FB := M 3.0 , BU := M 3.1 , TBIT := M 3.2 ); Thanks in advance:

Under "S5-S7 converting Blocks", you will find FC100 to FC107 which can be used for converting analog signals. These functions have the same input andoutput as your S5 block.

I have called FC100 in OB1 and passed the parameters to FC100 like your S5 plc code. Regards, Behnam www.sigmaprocess.ca Attachment S5_to_s7.zip (548 Downloads)

CHITTARANJAN Posts: 14 Rating: (0)	Thanks a lot. but i have one problem i.e. The have modified S7 program is like this: FUNCTION FC 143 : VOID VAR_TEMP lok_kcpar : array [0..1] of WORD; END_VAR BEGIN NETWORK OPN DB 80; NETWORK L 'P '; T lok_kcpar [0]; CALL FC 1050 (BG :=W#16#80 KNKT :=W#16#3 OGR :=16 UGR :=0 EINZ:=M0.0 XA :=DBW20 _FB :=M3.0 BU :=M3.1 TBIT:=M3.2); The above FC1050 is same as FC107 . Just renamed it!!! but when compile it, it showing Syntax error in the line KNKT:=w#16#3 Can u suggest any solution to remove this error!!!!!!!!!!!!! Thanks in advance!!!!!!!!!!!!

KD=22Fixed point format bipolar with nominal range -2048 to +2047 KD=23Value representation bipolar with nominal range -2048 to +2047 KD=24Fixed point format unipolar with nominal range 0 to +4095 KD=25Fixed point format unipolar with nominal range +512 to 2559 Regards, Behnam www.sigmaprocess.ca

CHITTARANJAN Posts: 14 Rating: (0)	Thanks for your reply. I had gone through FC-107 [FC1050] help manual and below attachment document.It was written like this. A process image of the S5 I/O areas P/Q/IM3/IM4 is made in the S7 I/O area. You must assign the I/O area in the configuration table. You must also match the address in the BG parameter (byte 2). What is the value in KNKD and setting in S7 hardware configuration so-that there will not any compile error!!! Modified S7 program: FUNCTION FC 143 : VOID VAR_TEMP lok_kcpar : array [0..1] of WORD; END_VAR BEGIN NETWORK OPN DB 80; NETWORK L 'P '; T lok_kcpar [0]; CALL FC 1050 (BG :=W#16#80 KNKD := OGR :=16 UGR :=0 EINZ:=M0.0 XA :=DBW20 _FB :=M3.0 BU :=M3.1 TBIT:=M3.2); Thanks in advance.

Based on whether your inputis bipolar or unipolar you have to select the right number from one of the 4 options. Regards, Behnam www.sigmaprocess.ca
