The CP 443-5 Extended provides access to different communication services of the PROFIBUS bus system: - PROFIBUS DP (according to IEC 61158/61784)
- PG/OP communication
- S7 communication (S7 controllers)
- Open communication (SEND/RECEIVE)
- Time synchronization
Master for PROFIBUS DP The CP 443-5 Extended operates as DP-V1 master. It processes data transfer autonomously and allows slaves to be connected, such as CP 342-5 as DP slave, DP slaves of the ET 200 distributed I/O system, etc. This means that the CP 443-5 Extended is able to connect the S7-400 station to PROFIBUS DP and is the ideal expansion to the integral DP master interfaces of the S7-400 CPUs for establishing additional PROFIBUS DP lines. The CP 443-5 Extended can also be used in the SIMATIC S7 H system as a redundant DP master. The CP 443-5 Extended is a DP-V1 master, i.e. it also supports the acyclic standard services incl. interrupt handling. The CP 443-5 Extended also supports the SYNC and FREEZE functions, constant bus cycle time, direct slave-to-slave traffic, data set routing and changes to the configuration of the assigned distributed I/O during normal operation. During normal operation, it is also possible to activate or deactivate DP slaves. This supports the step-by-step start-up of subprocesses, for example. A diagnostic repeater allows the line to be diagnosed during operation, enabling line faults to be detected at an early stage. The CP 443-5 Extended supports operation with diagnostic repeater (including activation of topology identification in the diagnostic repeater). The distributed I/Os are handled like central I/Os from the user's point of view. This means that there are no differences between the CP 443-5 Extended and the integral DP master interface of the S7-400 CPU with regard to configuration and parameterization. Depending on the scale of the system, the CP 443-5 Extended has extremely short response times. PG/OP communication PG/OP communication allows all S7 stations connected to the network to be remotely programmed. - S7 routing
With the aid of routing it is possible to use programming device communication across networks.
S7 communication S7 communication is used for the coupling - between SIMATIC S7 programmable controllers
- to programming devices (PG/OP communication)
- to PCs,
e.g. CP 5711 with SOFTNET-PB S7, CP 5623 etc. - to HMI devices (OPs).
For redundant S7 communication, the CP 443-5 Extended can also be used in SIMATIC H systems. Open communication (SEND/RECEIVE) SIMATIC S7-400 is integrated into existing systems by means of open communication. Based on Layer 2 (FDL) of PROFIBUS, the CP 443-5 Extended offers a simple, optimized interface for process or field communication. This interface offers uniform, high-performance communication between SIMATIC S5, SIMATIC S7 and the PC. It provides the services SDA (PLC/PLC connections) and SDN (Broadcast, Multicast). The communication partners are the programmable controllers - SIMATIC S7
with CP 342-5, CP 343-5, CP 443-5 Extended and Basic - SIMATIC S5
with S5-95U with PROFIBUS interface, S5-115U/H, S5-135U, S5-155U/H with CP 5431 FMS/DP - SIMATIC 505
with CP 5434-FMS - PCs
with CP 5512, CP 5611 A2, CP 5621, CP 5613 A3, CP 5613 FO, CP 5614 A3, CP 5623, CP 5624 - Non-Siemens systems that are equipped with an FDL interface.
To use SEND/RECEIVE, function calls are required (PLC-SEND/PLC-RECEIVE), which must be linked into the STEP 7 user program. Time synchronization Time synchronization is used to set the time of day throughout the plant. The CP 443-5 Extended is capable of forwarding the time of day of the S7-400 CPU to PROFIBUS. Conversely, the CP of the S7-400 CPU can make an existing time of day available on PROFIBUS The CP 443-5 Extended supports - The time-stamping of distributed process signals in combination with IM 153
- Time status value, daylight-saving time changeover, synchronization status
Data set routing The CP 443-5 Extended supports the data set routing function. With this option, the CP can be used as a router for data sets that have to be sent to field devices (DP slaves). SIMATIC PDM (Process Device Manager) is a tool that creates data sets of this type for parameterizing and diagnosing field devices. Application: It is possible, for example, to use SIMATIC PDM (on the PC) to set parameters and perform diagnostics for a PA field device over Industrial Ethernet, S7-400 (CP 443-1, CP 443-5 Extended) and DP/PA Coupler/Link. Diagnostics data Extensive diagnostic options are available via STEP S7, including: - Status of the CP
- General diagnostics and statistics functions
- Connection diagnostics
- Bus statistics
- Message buffer
- Support of operation with diagnostic repeater
CiR – Configuration in RUN With CiR, it is possible to add or modify distributed I/O devices during normal operation. - Adding PROFIBUS DP/PA slaves
- Adding/removing modules (e.g. I/O modules) in a modular DP slave (e.g. ET 200M and DP/PA Link)
Configuration STEP 7 V5.1 SP2 or higher, or STEP 7 Professional V12 (TIA Portal) or higher, is required for configuring the full functional scope of the CP 443-5 Extended. DP configuration/programming is performed for the CP 443-5 Extended in the same manner as for DP configuration/programming of the integrated DP interfaces of the SIMATIC S7-400 CPUs with STEP 7. The configuring data of the CPs are always saved on the CPU and are retained even after a PLC failure. A module can therefore by replaced without having to reload the configuration data from a programming device. The CPU transfers the configuration data to the CP during start-up. Configuration and programming of all SIMATIC S7 controllers connected to the network is possible over the network. The function blocks for using the open communication (SEND/RECEIVE) can be found in the SIMATIC NET library following installation of STEP 7.
