This just means reading Buffer memory area Hex E0 to E7 (8 words) and putting this data onto the bits M1000 - M1127
K4M1000 means 4 x 4 bits so M1000 - M1015 
The 8 on the end means batch read 8 consecutive reads BFM E0 E1 E2 etc.

Dear Gambit

You told me that " reading Buffer memory area Hex E0 to E7  " is this mean H0 to H0E0 equal to Hex E0 to E7 how can you convert them?

What is the BFM?

Thanks .

BFM (Buffer memory area ).

These are locations on a special module which you write and read from to setup the module and read the information.

H0 is the module's IO adress. this Doesnt change beacuse of the Batching of K8 only the BFM and devices.
