Delta DTM Series - RUN;STOP Status at Power on

Chapter 2: Specifications and System Configuration
DTM temperature controller operating manual
2-11
Internal communications error Other error
Hx9B8 Hx9B0~Hx9B7 (input channels 1~8)
Bit0 There are more than 7 measurement
expansion modules
Input temperature value is unstable (any
input point)
Bit1 Main station data collection error Sensor input line is severed or not
connected (any input point)
Bit2 Internal communications line severed Input sensor error (any input point)
Bit3 Expansion modules of the same type
have the same internal station
number
Input hardware malfunction (any input
point)
Bit4 Communications write error Memory EEPROM error
Bit5 Communications read error Input exceeds setting range (any input
point)
Bit6 N/A A program has exceeded wait time (only
notifies, does not run)
Bit7 N/A RTD input short circuit (any input point)
Table – Corresponding error status table
 Example: If it is found that the reading of measurement expansion module input channels 3 in internal station
number 2 is abnormal, the error indicator light will come on, the command to read address [H 29B2] and confirm
the situation can be given.
 Notes: x indicates the internal station number of the host or measurement expansion module.
 Please pay special attention to that the DTM system cannot automatically detect the error of the internal
station number of the same type of IO expansion module. The following IO expansion module models
are of the same type, DTM-DOV, DTM-DOR, DTM-DOC, DTM-DOL, DTM-DOX.
2.7.2 RUN/STOP Status at Power ON
According to bit0 of Hx1E6, set the STOP/RUN status of DTM when powering on, setting content
0=RUN(default) at power ON, 1= STOP at power ON
