Technology module TM FAST (6ES7554-1AA00-0AB0)
13 Equipment Manual, 04/2023, A5E52301130-AA
3.1 Pin assignment
You connect input and output signals to the 40-pin front connector of the technology
module. In addition, you connect the supply voltage for supplying the module and the digital
outputs to the 4-pin infeed element. Some of the connections can be used as an input or
output. You define this in the TM FAST (Page 41) application.
For information on wiring the front connector, connecting the cable shield, etc., see System
Manual S7-1500, ET 200MP Automation System
(http://support.automation.siemens.com/WW/view/en/59191792), section Wiring.
Shielded cables are usually required depending on the output frequency used and the
configured input delay. Shielded cables are not required for input delays of 100 µs and more.
If the shield connection element is not sufficient, you can additionally use the S7-300 shield
connection terminals specified in section Properties (Page 10).
Electromagnetic compatibility
The high-frequency switching (> 5 kHz) of the 24 V outputs generates electromagnetic
feedback effects on the supply network. You have the following options for adhering to the
limits that correspond to the current state of the art:
• Use a separate 24 V power supply unit, e.g. SIMATIC PM 1507 24 V/3 A (article number
6EP1332-4BA00), to supply the TM FAST.
• Provide a corresponding filter for the 24 V supply. The interference radiation
measurements were made with filters of the type "EPCOS SIFI-C B84113C". Use this filter
type or a filter with the same characteristic or a characteristic with greater damping.
• Take appropriate measures already when generating the output signals, e.g. "frequency
dithering" of the generated output frequencies.
