Banner SC22-3E Safety Controller with Ethernet - Manual (Page 125)

• Instance ID 102 (0x66) with a size (data length) of one hundred forty 16-bit words. Instance ID 102 is used to access fault log infor-
mation (it provides no Virtual Status Output information). The format of the fault log information starts with a time stamp and may be
found in the appropriate Fault Log Support file (see section
11.3 Support Files on page 125).
Output (O->T) Assembly Object
The Output Assembly Object is not implemented. However, some EtherNet/IP clients require one. If this is the case, use Instance ID 112
(0x70) with a data length of two 16-bit words.
Configuration Assembly Object
The Configuration Assembly Object is not implemented. However, some EtherNet/IP clients require one. If this is the case, use Instance
ID 128 (0x80) with a data length of 0.
11.3 Support Files
During installation of the PCI, the following support files are copied to the computer’s Program Files directory (C:\Program Files\Banner
Engineering\Banner SC\Network Tables), in both .csv and .pdf formats. These files contain network communication information and fault
diagnostic information. To access the files, use your computer’s navigation tools (e.g., “My Computer” or Windows Explorer).
Any references in this section to files are referring to these support files. All of these files are also available on www.bannerengineer-
ing.com .
• Fault Index Table (applies to all protocols)
• MB Fault Log
• MB System Info
• EIP Fault Log
• EIP Fault Log Explicit Messages
• EIP System Info Explicit Messages
• PCCC Fault Log
• PCCC System Info
An additional file is included with a .eds format. This file is a simple text file used by network configuration tools to help identify products
and easily commission them on a network.
11.3.1 Retrieving Current Fault Information
To retrieve information via network communications about a fault that currently exists, the following procedure may be used:
1. Read the Fault Flag location. If this location is set, then a fault exists.
2. Read the Fault Index location. The number in this location provides an index value used with a Fault IndexTable file that contains
fault diagnostic information.
3. Access the data in the Fault Index Table file using the Fault Index number. The data in the file provides a specific fault number, a
short fault description, a longer fault description, and a remedy.
11.3.2 Retrieving Fault Log Information
To retrieve information via network communications about faults contained in the fault log, the following procedure may be used:
1. Read the number in the Seconds Since Power-up location in the appropriate System Info file. The number indicates, in seconds,
how long the Safety Controller has been ON.
2. Compute the real time that the Safety Controller powered up (e.g., hour, minute, second) by using the Seconds Since Power-up
number with a real time reference.
3. Read the number in the Time Stamp location in the Fault Log file. The number indicates, in seconds, when the fault happened,
relative to a power-up.
4. Compute the real time when the fault occurred by using the Time Stamp number with the power-up time of the Safety Controller,
computed in Step 2.
5. Read the Fault Index location in the Fault Log file. The number provides an index value used with a Fault Index Table file that
contains fault diagnostic information.
