Linkage with PLC
120 VIPA GmbH CP486 ⋅ 00/14
ZT/N: D KY left byte: reserve
right byte: target module no. (2...255), DB-no. of
the module with data to be transferred is specified
ZANF: D KF Initial address in DB (0...32761), the DW-no. is specified from
whichonthedatatobetransferredarefiledintheDB.
ZLAE: D KF Number of data words (1...504) at least to be transferred,
CP passes only so many data words as it also supplies.
PAFE: A BY Markerbyte, in which the PAFE-message is transferred to
PLC program (permitted 0...255)
Error acknowledge message of handling module:
= 0 no error occurred
><0 error occurred, error number in PAFE-Byte:
3 basic bank number is not divisible by 8
4 bank not existent (acknowl. delay at access)
5 bank is not synchronized yet by the CP
10 invalid job number (out of 1...127)
12 no DB open for indirect parameterization
13 source module is not existent
14 source module too short
15 ZLAE is invalid (out of 1...504)
16 DB for indirect parameterization too short
18 invalid target module no. (out of 2...255)
19 invalid target initial address (out of 0...32761)
20 invalid marker word no. for ANZW (out of 0...198)
Attention: error number 4 in PAFE is dedicated for future improvements. In the moment, it is generally not
possible to recognize QVZ via software in the CPUs for the PLC-115. In this version, the CPU goes in QVZ in
stop, if the bank number of the CP does not coincide with the number being parameterized in this module.
Parameter storage in a DB if parameterization is indirect:
DL DR
A-NR points to the beginning
INSS
A-NR
ANZW
ZT/N
ZANF
ZLAE
PAFE is not parameterizable indirectly
0 can be parameterized at all other formal operands (SS,, ANZW, ZT/N, ZANF, ZLAE) because
these are not evaluated at indirect parameterization.
