7.4 Reading via Communication

When reading the alarm status
Read I relay numbers 4321 to 4336 for Loop-1 alarm-1 to alarm-8 status.
I relay No. Symbol Event
4321 to 4336 ALM1_L1~ALM8_L1 Loop-1 alarm-1 to alarm-8 status (Same as D2011) *
4337 to 4352 ALM1_L2~ALM8_L2 Loop-2 alarm-1 to alarm-8 status (Same as D2013)

*: The contents of Loop-1 alarm-1 to alarm-8 status (I relay numbers 4321 to 4336:
ALM1_L1 to ALM8_L1) are the same as the bit configuration of D register number
D2011 (Loop-1 alarm-1 to alarm-8 status). Refer to the bit configuration of D2011
described in “Chapter 6 Functions and Applications of D Registers (for UT55A/UT52A/
UP55A).”
The following shows the bit configuration of D2011 described in “Chapter 6 Functions
and Applications of D Registers (for UT55A/UT52A/UP55A).”

Bit Configuration of D2011: ALM_L1 (Loop-1 alarm-1 to alarm-8 status)
Bit Symbol Event
0 ALM1_L1 ‘1’ when Loop-1 alarm 1 is ON; ‘0’ when OFF
1 ALM2_L1 ‘1’ when Loop-1 alarm 2 is ON; ‘0’ when OFF
2 ALM3_L1 ‘1’ when Loop-1 alarm 3 is ON; ‘0’ when OFF

Note
When specifying an I relay number for communication, begin the number with the character “I.”
Example: Set “I4321” to specify the ALM1_L1 (I relay No.: 4321).
