3401 Manual
Point I/O Stepper Module
Revision 2.0
20. The following tags will have been created. The adapter name shown here was selected for the
1734-AENT in Step 5 above. Also, X = slot number and Y = word number.
adapter_name:X:I.data[Y] Input Data sent from the 3401 module to the PLC. Words 0
and 1 will always be zero.
adapter_name:X:O.data[Y] Output Data sent from the PLC to the 3401 module.
adapter_name:X:C.data[Y] Configuration Data, not used by the 3401 module.
21. Save the project.
22. Download the new configuration to the processor.
Installing the 3401 module in a Profibus system
SST-PFB-SLC Profibus interface module to AB 1734-APB
1. If it is not already present, install the SST-PFB-SLC module in the SLC rack and configure the rack
(the ID code is 13635) for the module.
2. Place the PLC in program mode.
3. Connect a serial cable from the computer’s COM port to the RS232 port of the SST-PFB-SLC
module.
4. With the power off, set the station address 1734-APB.
5. Attach the 1734-APB to the Profibus network.
6. Apply power to the 1734-APB.
7. Start the SST Profibus Configuration software.
8. Either create a new or open an existing network.
9. To use the AMCI 3401 module in a Profibus Point I/O system, it must be added to the GSD file
for the 1734-APB. There are two options.
a. Download the 1734-APB file that already contains the AMCI 3401 module. This file is
named 1734AMCI.gsd and will replace the GSD file that is currently being used to
communicate with the 1734-APB
b. Use a text editor to add the AMCI 3401 information to your existing 1734-APB GSD
file. This file is named 3401_Profibus.txt. After you have added it, register the
modified GSD file with your Profibus network software.
The ZIP file containing these two files is named AMCI_3401_Profibus.zip and are
available for download from the Tech Library section of our website, www.AMCI.com.
Because the data from the 3401 module is updated at the RPI time
asynchronously to the program scan, AMCI recommends that the input data
be buffered before it is used by the ladder logic program.
Because of the communication parameters that it stores in the module’s
memory, once a 3401 module has been used with a 1734-APB, it may not
operate in a Point I/O system that is based on a different network.
