System Description S5-95U, SINEC L2
Communications with the CP 5410 and/or CP 5430-1
You must set the same basic parameters BDR, SET, ST, SDT 1 and SDT 2 for the S5-95U, CP
5410 and CP 5430-1.
Define the arguments of the BDR, SET, ST, SDT 1 and SDT 2 basic parameters as shown in Table
1-4:
• for the S5-95U in DB1
• for the CP 5410
• for the CP 5430-1

Example: Define the baud rate as 187.5 kbaud in DB1. This gives the other basic parameters
as follows: SET 1 ST 380 SDT 1 12 SDT 2 150.
Communications with Other SIMATIC Devices, e.g. the CP 5412 or CP 5430-0
You must set the same basic parameters BDR, SET, ST, SDT 1 and SDT 2 for the S5-95U and the
other SIMATIC device.
Define the arguments of the BDR, SET, ST, SDT 1 and SDT 2 basic parameters as shown in Table
1-5:

• for the other SIMATIC device
