PA: Remote Operation
Acyclic Extended Diagnostics (General Fault Codes)
In addition to the extended diagnostics available by cyclic data exchange (shown above),
further extended diagnostics are available via acyclic communications. This consists of
six bytes. See
Appendix B: Asynchronous Communications Data Map
on page 58 , for the
location of Extended Diagnostics
For a table listing the fault codes, meanings, and suggested corrective action to take, see
General Fault Codes
on page 88.
Acyclic Data
SITRANS LR 460 supports up to four simultaneous connections by a Class 2 Master
(C2 connection). It supports one connection by a Class 1 Master (C1 connection). A list of
all acyclic data, including address (slot and index), format, range of values, start value,
and attributes, can be found at
Appendix B: Asynchronous Communications Data Map
on page 58.
Configuration Example
To configure and use PROFIBUS PA with an S7-300/ 400 PLC
1. If SITRANS LR 460 is not listed in the STEP 7 device catalog, you can download the
DeviceInstall file from the Siemens Milltronics Web site and run it from your
computer. Go to https://pia.khe.siemens.com/index.asp?Nr=7427
and click
Downloads.
2. Add the SITRANS LR 460 "rack": click and drag the SITRANS LR 460 folder from the
hardware catalog.
3. Fill the rack with desired modules, by dragging and dropping them from the
hardware catalog.
4. After configuring PROFIBUS PA in steps 2 and 3, download it to the PLC.
5. Add code to the PLC program to read data consistently using the SFC14.
