5 MPI Communication
5.7 Handheld terminal HT 6
Programming device (e.g. PG740)
A programming device/PC is required for the SIMATIC Manager STEP7 as the
platform in order to match the basic PLC or PLC user program to the require-
ments of the appropriate automation system with regard to the operation of an
HT 6 and to load it then into the PLC. For adapting the basic PLC or PLC user
program, see Chapter 8, page 8-249.
A programming device/PC is not required if the SIMATIC Manager STEP7 is
installed on the SINUMERIK 840Di.
The installation of additional software on the SINUMERIK 840Di is described in
Chapter 15, page 15-455.
A PC/programming device is also required if the HT 6 user interface or the MPI
address is modified using the HT 6 system software and the whole modified
software is then to be loaded into the HT 6.
The following software components are required to start up the HT 6:
Basic PLC program
The basic PLC program is included on the SINUMERIK 840Di installation CD.
HT 6-relevant modules of the basic PLC program are FB 1 (HT 6/PLC commu-
nication) and FC 26 (NC/PLC communication).
For the archiving location of the basic PLC program, please refer to Section 1.2,
For the use of the basic PLC program, please refer to Chapter 8, page 8-249.
SIMATIC Manager STEP7
SIMATIC Manager S7 is used for adapting the basic PLC user program (e.g.
parameterization of FB 1).
HT 6 system software (optional)
The HT 6 system software (CD-ROM) provides the following possibilities:
– Language selection for the 1st and 2nd Language
– Creation of the user's alarm texts
– Modification of the MPI address
Order No. (MLFB): 6FK5 453-jAX10-jAG0 (version-dependent)
The following manuals are required to start up the HT 6:
