Various Interface Signals (A2)
1.4 Signals from PLC to HMI
The use of the numbers is divided into the protection areas of the programs:
● 1 to 100: User area (end user protection level)
● 101 to 200: Machine manufacturer (machine manufacturer protection level)
● 201 to 255: SIEMENS (SIEMENS protection level)
The file PLCPROG.LST - where the minimum protection level for end user has been set -
can be edited using the operation: "System" -> "PLC" -> "Program list" or by using the
standard editor (program manager -> User cycles). The protection level for the editor should
be at least the machine manufacturer protection level.
This file can also be created externally and loaded to the control via the PCIN tool / V.24
interface. The following structure specification must be observed, header entry first:
%_N_PLCPROG_LST
;$PATH=/_N_CUS_DIR
Each line contains two columns. These are separated via tabs or blanks or " | " characters.
The first column contains the program number, the second the program name.
Examples:
%_N_PLCPROG_LST
;$PATH=/_N_CUS_DIR
1|BOHR2.MPF
2|PUMPT14.MPF
54|BOHR3.MPF
"Program number" (VB 1700 1000) corresponds to the following IS:
● "Program has been selected" (V1700 2000.0)
● "Program selection error" (V1700 2000.1).
When a program number > 0 is written, the program selection is started by the PLC. As soon
as the HMI detects a program number > 0, it begins with the internal processing of this job
and sets the program number (VB 1700 1000) to 0.
PLC waits until the acknowledgement signal from HMI is received: V1700 2000.0 or V1700
2000.1 and evaluates this immediately. The acknowledge signals are available for one PLC
cycle once they have been received and are then automatically deleted by the PLC
operating system.
Command (VB1700 1001)
A command job is transferred from the PLC to the HMI.
