Integration

Distributed ET 200iSP stations are connected to the SIMATIC

PCS 7 automation systems (controllers) via the PROFIBUS DP,

which can be routed intrinsically-safe into Ex zone 1 using an

isolating transformer (RS485-iS coupler) as barrier. Data transfer

rates of up to 1.5 Mbit/s are possible.
The modern architecture with independent wiring and automatic

slot coding supports simple and reliable hot swapping of individ-

ual modules without a fire certificate. To increase plant availabil-

ity, both the power supply and the PROFIBUS DP interface can

be of redundant design.

The ET 200iSP is integrated into SIMATIC PCS 7 using standard

driver blocks. You can therefore configure and parameterize the

ET 200iSP in the SIMATIC Manager of the engineering system

extremely simply using HW Config. The system function CiR

(Configuration in Run) is also supported, and permits the follow-

ing changes to be made to the configuration during runtime:
• Adding of an ET 200iSP station
• Adding of a module in an ET 200iSP station
• Reparameterization of modules.
Vendor-specific information and maintenance data are saved

powerfail-proof on the electronics modules.
The existing standard diagnostics drivers preprocess the diag-

nostics messages generated by internal or external faults (e.g.

wire breakage or short-circuit) as well as status messages of the

connected HART field devices for the host operator system and

the maintenance station of the PCS 7 asset management. The

ET 200iSP and the HART field devices can also be parameter-

ized using SIMATIC PDM (process device manager). With SI-

MATIC PDM you can directly access the HART field devices on

the ET 200iSP by routing via PROFIBUS DP.
