The order of the byte forming the floating-point registers can also be configured remotely
through writing to the coil registers.
Coil registers 16 and 17 enact this functionality with the logic table outlined below.
Coil register 16
0
1
0 0 Big endian
0 Big endian byte swap
1 Little endian
1
1 Little endian byte swap
Coil register 17 Floating point register
Function code “1” read.
Function code “5” write.
This is a read/write register containing the instrument binary settings, including alarm status,
PM units and 4 - 20 mA output “Enable”/“Disable” status.
Writing to this register will result in the setting being changed permanently. However, if an
alarm is activated, writing to the alarm status coil will dismiss the active alarm until the alarm
threshold parameters have been re-exceeded.
