CMP is compared to check the block is a LX3V-4AD, if OK M1 is turned ON.
269 +In the following example channels CH1 and CH2 are used as voltage inputs. The LX3V-4AD block is connected at the position of special function block No.0. Averaging is set at 4 and data registers D0 and D1 of the PC receive the averaged digital data.

381 381  1. The operational status of the LX3V-4AD is read from BFM #29 and output as bit devices at the LX3V main unit. If there are no errors in the operation of the LX3V-4AD, then the averaged data BFM’s are read.
382 382  1. In the case of this example BFM #5 and #6 are read into the LX3V main unit and stored at D0 and D1. These devices contain the averaged data for CH1 and CH2 respectively.
