Properties of the DP/PA Coupler (General)
The DP/PA coupler has the following characteristics:
S
Electrical isolation between PROFIBUS-DP and PROFIBUS-PA
S
Conversion of the physical transmission mechanism between RS-485 and IEC
61158-2
S
Diagnostics using LEDs
S
Transmission rate on PROFIBUS-DP 45.45 Kbps
S
Transmission rate on PROFIBUS-PA 31.25 Kbps
S
Integrated power supply unit
Properties of the DP/PA Coupler Ex [i]
The DP/PA coupler Ex [i] (6ES7 157-0AD00-0XA0) has the following additional
characteristics:
S
Type of Protection EEx [ia] II C
S
Intrinsic safety
S
Integrated, intrinsically safe power supply unit and integrated barrier
The DP/PA coupler Ex [i] (6ES7 157-0AD80-0XA0) has the following
characteristics that differ from the DP/PA coupler EX [i] (6ES7 157-0AD00-0XA0):
S
Type of protection EEx [ib] II C
S
Extended environmental conditions (SIMATIC outdoor)
Configuring the DP/PA Coupler
S
The DP/PA coupler can be used in SIMATIC S5 and S7 and with all DP masters
that support 45.45 Kbps.
S
The DP/PA coupler does not need to be configured. You must only set the
transmission rate of 45.45 Kbps for the relevant DP network during
configuration.
You then configure the PA field devices just as normal DP slaves using the DP
configuration tool and the appropriate GSD file. You can configure the PA field
devices with SIMATIC PDM or with any other vendor-specific software
configuration tool.
