8.1 General Information
The BCL 34 with MS 34 103/MS 34 105 was developed as a PROFIBUS device. The func-
tionality of the device is defined via parameter sets which are clustered in modules. These
modules are included in a GSD file, which is supplied as an integral part of the device. By
using a user-specific project tool, such as, e.g., Simatic Manager for the programmable
logic control by Siemens, the required modules are integrated into a project during
commissioning and its settings and parameters are adjusted accordingly. These modules
are provided by the GSD file.
All input and output modules described in this documentation are described from the
controller's perspective:
• Input data arrives at the controller
• Output data is sent out by the controller
Preparing the control system for consistent data transmission
During programming the control system must be prepared for the consistent data transmis-
sion. This varies from control system to control system. The following possibilities are
available for the Siemens control systems.
S7
The specific function blocks SFC 14 for input data and SFC 15 for output data must be inte-
grated in the program. These are standard function blocks and are used to facilitate
consistent data transmission.
S5 with IM 308C
• Up to Release 5 together with Comprofibus software up to Release 2 and
• Release 6 and above together with Comprofibus software Release 3 and above
Here, the function block FB 192 must be integrated, which is used to transmit the
consistent data.
S5 with IM 308B
With the IM 308B consistent data transmission must be programmed via load transfer
commands.
