Help with Sattcon logic conversion

Hello,

I am in the process of converting a program written for a Sattcon 15 controller into a RSLogix 5000 ladder logic program.

While I have a brief manual and the conversion works decently smooth, I have a couple of "rungs" that don't make sense to me. I am hoping that somebody here can shed some light. Here are the two lines of logic:

0102 :
00 A MIX_MT_START 0034 EMPTY MIX TANK START
01 A MIX_TO_TK3 0021 PUMP MIX TANK TO TK3
02 RP
03 O MIX_TO_TK3 0021 PUMP MIX TANK TO TK3
04 A MTMT_TO_T3 0562
05 RP
06 A MIX_MT_STOP 0027 STOP EMPTYING MIX TANK
07 = MTMT_TO_T3 0562
*



0154 :
00 A FILL_ACID_COP 0702 OUTPUT TO FILLING ROOM COP TANK
01 O FILL_ACID_DIS 0703 OUTPUT TO FILLING ROOM DISPENSER
02 RP
03 = FLLR_ACID_REQ 0147
04 RP
05 AN ACID_RQ_VTIS 1761 ACID GOING TO VTIS
06 AN ACID_RQ_PLAT 1766 ACID GOING TO PLATE
07 AN ACID_RQ_CIP1 1767 ACID GOING TO CIP IN BLENDING
08 = ACID_REQ_FILL 1470
*



What causes the problem with code "0102" is the use of RP on line 02.

the problem with code "0154" is the use of = sign in the middle of the logic statement.

Any help with this would be tremendous.
