This driver uses the Sinec L2 Profibus FDL
interface. It requires the use of:
- Siemens CP5412A2 card.
- The Siemens DP5412 software for Windows 95 or Windows NT.
- The PLC specific communications hardware and software as
defined in the following sections.
For S5-95U Communications
In addition to the items listed above, the Citect driver requires
the following S5-95U components for Sinec L2 Profibus FDL
communications to S5-95U series PLCs:
- The built in L2 interface port.
- Some special PLC software called a Communications Function
Block. This software must be loaded into the PLC using the Siemens
programming software.
For S5-115U/H, S5-135U/H, S5-155U/H
Communications
In addition to the items listed above, the Citect driver requires
the following S5-115, S5-135 or S5-155 components for Sinec L2
Profibus FDL communications to any S5-115, S5-135 or S5-155
communications:
- The CP5431 FMS/DP communications processor.
- Some special PLC software called a Communications Function
Block. This software must be loaded into the PLC using the Siemens
programming software.
This driver will not be offered in a 16 bit version by choice of
Ci Technologies. The 16 bit equivalent Citect SINECFDL driver uses
the older CP5412 (A1).
*Note that there is a possibility that the following files are
not automatically added to the bin directory if you install the
SFDL driver:
- CIT115ST.S5D
- CIT135ST.S5D
These files are required for the SFDL communication functions
with the SFDL driver.
If you find that after you have installed the SFDL driver
that these files are NOT in the BIN directory, then copy the
files (see attachment) to your BIN directory
