6.8.5. User Data (60H – 6F)
There is a section in memory that allows the user to store information. This is useful if the physical
location or other user identification is required. The only restriction on the information is it must be
Modbus compatible. Only one word can be written per command. There are a total of 16 words for the user.
6.8.6. Comm 2 Bus Activity Rate % (71H)
A read indicates the Comm 2 Bus Activity Rate in percent of this slave's addressed node versus other
addressed nodes. Range of this value is in hex (0-64), which translates to decimal (0-100%).
6.8.7. Comm 2 Function Code Errors (72H)
A read indicates the number of Comm 2 Function Code Errors that occurred in the slave device. The
maximum count is 65535 and then the counter rolls over to zero and begins counting again.
6.8.8. Comm 2 Starting Address Errors (73H)
A read indicates the number of Comm 2 Starting Address Errors that occurred in the slave device. The
maximum count is 65535 and then the counter rolls over to zero and begins counting again.
6.8.9. Comm 2 Total Receive Errors (74H)
A read indicates the total Modbus Comm 2 Only Receive Errors that occurred in the slave device.
These are address, function, etc. type of errors. The maximum count is 65535 and then the counter
rolls over to zero and begins counting again.
6.8.10. RXD CRC Errors Hi (75H)
A read indicates the number of RXD CRC Errors that occurred in the slave device. The maximum
count is 65535 and then the counter rolls over to zero and begins counting again.
6.8.11. RXD CRC Errors Lo (Same as Hi) (76EH)
NOTE:
Hi and Lo CRC errors are reported in the same word. A read from either Hi or Lo will return
the same count.
6.8.12. Comm 2 Parity Errors (77H)
A read indicates the number of Comm 2 Parity Flag Errors that occurred in the slave device. The
maximum count is 65535 and then the counter rolls over to zero and begins counting again.
