Specify the type of thermocouple, H3310 -> Block No.2 BFM#0. CH3 & CH4 are not used;
CH2: Type J (1); CH1: Type K (0);
Block No.2 BFM#30->(D2) identification code;
When (K2030)= (D2), M1=ON. i.e. when identification code is K2030, M1=ON.

Example 2
This step provides optional monitoring of the LX3V-4TC Error Buffer Memory (#29). If there is
an Error on the LX3V-4TC, bit b0 of BFM #29 will be set on. This can be read by this program
step, and output as a bit device in the PLC (Y010 in this example). Additional Error devices can
be output in a similar manner, e.g. b10 BFM #29 Digital range error. (see example 3)

Example 3
(K4)-> (BFM#1), (K4)-> (BFM#2). Number of samples is changed to 4 on both CH1 and CH2.
(BFM#5)-> (D0), (BFM#6)-> (D1). Transfer the average temperature value in °C to the data
registers.
This step is the actual reading of the LX3V-4TC input channels. It is essentially the only program
step which is needed. The "TO" instruction in this example, sets the input channels, CH1 and
Transfer the error status to (M25
to M10), when error is found,
M10=ON
M10 represents b0 of BFM#29
M20 represents b10 of BFM#29
