RESPONSE DATA BYTES
#0 #1 #2
CUTOFF CUTOFF CUTOFF
CONTROL ON OFF
VALUE VALUE
Data Byte #0 Cutoff control variable:
0 - to switch cutoff option Off ,
Any other value - to switch cutoff option On.
When the cutoff option is switched from On to Off, the rest data in request packet is ignored
and therefore On/Off Values will not be altered in transmitter EEPROM.
Data Byte #1 Cutoff On Value, in 1/10% of the Primary Variable Upper Range Value (say, 5% will result
in a value of 50 on a bus). This byte is meaningful only if Data Byte #0
≠
0. Value must
belong to interval 10..190 (1..19%).
Data Byte #2 Cutoff Off Value, in 1/10% of the Primary Variable Upper Range Value. This byte is
meaningful only if Data Byte #0
≠
0. Value must belong to interval 20..200 (2..20%).
Refer also to comments for the previous command.

8.7 Command #136 Stop/Resume Totalizers
Depending on the value of control variable all totalizers are either frozen (regardless of measurement process) or
resumed. After resumption frozen values are being initial ones for every totalizer. When totalizers are stopped,
Commands #3, #33 will return for Transmitter Variables 2..3 corresponding constant (frozen) values.
