• Check whether or not channel data is being read or written correctly
by "status at read" or "status at write", respectively.
• The following shows the check bits of each channel. These bit assign-
ments are the same for both "status at read" or "status at write".

• "0" indicates a normal channel, and "1" indicates a channel in error.
For example, if channels 5 (CH5) and 3 (CH3) are in error, bits 4 and
2 become "1". Data is expressed as "0014" (Hex).
• Check the internal status of E5EK-DRT by "status A" or "status B."
• The following table shows the meanings of "status A" bits:
Bit Description
0 Heating side output
1 Cooling side output
2 Alarm output 1
3 Alarm output 2
4 Alarm output 3
5 LBA output
6 HBA output
7 Run/Stop
8 Auto/Manual
9 Remote/Local
10 SP mode
11 Auto-tuning

*1 Always "OFF" at linear output
*2 Always "OFF" when output is not assigned
• The following table shows the meanings of "status B" bits:
