HB97E - CPU - RE_21x-2BS03 - Rev. 15/16

The following text shows the approach of programming in easy steps:

Start-up OB100:

•

Call SYNCHRON with SFC 235 and enter the wanted block size (Page
frame basic address=0, Block size, PAFE)

•

Parameterize the interfaces with SEND (SFC 230) with order no. 201
and parameter DB

•

To take over the parameters, you call RESET (SFC 234) with order no. 0

Cycle OB1:

•

Create SEND and RECEIVE orders for send and receive initialization

•

Create SEND ALL and RECEIVE ALL orders for user data transfer

A more detailed description follows.
