Model IR400 MODBUS
16
1.4.15 Alarm Level (0x0018)
Sets/reads minimum gas concentration level in % of Full Scale, when alarm event is
logged
1.4.16 Warn Level (0x0019)
Sets/reads minimum gas concentration level in % of Full Scale, when warn event is
logged
1.4.17 HART Configuration (0x001A)
0 in low byte means HART disabled, 1 – HART enabled. 0 in high byte means low
current range (1.25 -20 mA), 1 - high current range (3.5 – 20mA).
1.4.18 Total Receive Errors (0x0020)
A read indicates the total Modbus Comm. Receive Errors that occurred in the slave
device. The maximum count is 65,535; the counter will roll over to zero and begin
counting again. The total errors are an accumulation of the individual Comm. errors listed
below.
1.4.19 Function Code Errors (0x0022)
A read indicates the number of Function Code Errors that occurred in the slave device.
The maximum count is 65,535 the counter will roll over to zero and begin counting again.
1.4.20 Starting Address Errors (0x0023)
The counter is incremented for illegal register address.
A read indicates the number of Starting Address Errors that occurred in the slave device.
The maximum count is 65,535; the counter will roll over to zero and begin counting again.
1.4.21 CRC Hi Errors (0x0025)
A read indicates the number of CRC Hi Byte Errors that occurred in the slave device. The
maximum count is 65,535; the counter will roll over to zero and begin counting again.
1.4.22 CRC Lo Errors (0x0026)
A read indicates the number of CRC Lo Byte Errors that occurred in the slave device.
The maximum count is 65,535; the counter will roll over to zero and begin counting again.
1.4.23 Overrun Errors (0x0027)
A read indicates the number of Overrun Errors that occurred in the slave device. The
maximum count is 65,535; the counter will roll over to zero and begin counting again.
1.4.24 Framing Errors (0x0029)
A read indicates the number of Framing Errors that occurred in the slave device. The
maximum count is 65,535; the counter will roll over to zero and begin counting again.
1.4.25 Clear Communication Errors (0x002D)
A read or write resets all the Modbus Comm. Error counters to zero.
