RE10TC Temperature Control Module Operating manual

Details of the real values Buffer Memory
3.2.3 State of the digital outputs (BFM #20 and BFM #21)
These two data words are used to indicate the states of the outputs of the RE10TC:
BFM #20: State of the digital outputs for heating
Bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Controller
10 9 8 7 6 5 4 3 2 1
Output
YH9 YH8 YH7 YH6 YH5 YH4 YH3 YH2 YH1 YH0
BFM #21: State of the digital outputs for cooling
Bit 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Controller
10 9 8 7 6 5 4 3 2 1
Output
YC9 YC8 YC7 YC6 YC5 YC4 YC3 YC2 YC1 YC0

3.2.4 State of the alarms and warnings (BFM #22 to BFM #25)
The flags in these four data words indicate which of the analog inputs have reached a limit or
warning value. A flag is ON as long as the real value has exceeded the limit or warning value.
The flag is reset when the real value of the input is back inside the border of the limit. If the real
value for example becomes smaller than the upper limit, the respective flag turns OFF.
BFM #22: Actual value smaller than lower limit
BFM #23: Actual value larger than upper limit
BFM #24: Actual value smaller than lower warning
BFM #25: Actual value larger than upper warning

Bit = 1: Output is ON.
Bit = 0: Output is OFF
Bit = 1: Limit/warning reached
Bit = 0: Limit/warning not reached
