S5-95U, SINEC L2
4.2
Assigning Parameters in DB1 of the S5-95U for Data Exchange with
Standard Connections
You assign the following parameters in DB1:
•
The location of the send mailbox (SM).
•
The location of the receive mailbox (RM).
•
The location of the send coordination byte (CBS).
•
The location of the receive coordination byte (CBR).
SF, EF, CBS, and CBR are used with the L2 bus of the S5-95U the same way as with the SINEC
L1 bus. Refer to chapter 14 of the S5-90U/S5-95U Programmable Controller System Manual for
additional information.
DB1 with the default parameters for standard connections is represented in Figure 4-3.
The procedure for parameterizing, modifying and transferring the DB1 parameter block is described
in detail in section 1.4.
