S5-95U, SINEC L2 Programmer Functions Over the SINEC L2 Network
9 Programmer Functions Over the SINEC L2
Network
This chapter will show you
• which programmer functions can be implemented over the SINEC L2 LAN for the S5-95U,
• how to establish the connection to a remote station from the programmer, and
• how to activate the connection.
You can operate the programmer as a station on the SINEC L2 LAN. Address TLN 0 is reserved for
the programmer.
Prerequisites:
To program the S5-95U over the SINEC L2 LAN, you must assign the necessary SINEC L2 interface
parameters in DB1.
At least the basic parameters must be in DB1. You will find tables of the basic parameters in section
1.4 of the manual. You must set these parameters in the S5-95U for the CP 5410 (PG 730/750/770
programmers) or CP 5412 (PG 685 programmer).
Important: Programmer functions over the SINEC L2 LAN can only be implemented for active S5-
95Us. Station status "STA AKT" must therefore be specified as a basic parameter in
DB1.
FMA services and the standard connection, PLC-to-PLC connection and cyclic I/O types of data
transmission, and layer 2 services can also be configured in addition to the programmer functions.
Note:
If you switch the PLC from STOP to RUN following a "PLC overall reset", the SINEC L2 interface
parameters are not set and the PLC cannot be programmed over the SINEC L2 LAN.
Reason: Following a "PLC overall reset" and a change from STOP to RUN mode, the default DB1
is again valid in the PLC. The SINEC L2 parameter block is within comment characters (#)
in default DB1, and is therefore not interpreted by the PLC.
Remedy: Overwrite each comment character with a blank character; set the basic parameters
( section 1.4); transfer the modified DB1 to the PLC, and switch the PLC from STOP to
RUN mode.
To reach an S5-95U over the SINEC L2 LAN from the programmer, you must edit the corresponding
path with the programmer's "Bus dialling" utility and store this path in a path file.
You can then activate the edited path for the particular station.
You need S5-DOS (version V and later) to select a remote station over the SINEC L2 LAN.
The following programmers can be operated currently as stations on the SINEC L2 LAN:
• PG 685 (together with CP 5412)
• PG 730 (together with CP 5410B or CP 5410B/FlexOS)
• PG 750 (together with CP 5410B or CP 5410B/FlexOS)
• PG 770 (together with CP 5410B or CP 5410B/FlexOS)
