The CP 1542SP-1 IRC communications processor connects the ET 200SP Distributed Controller with Industrial Ethernet networks. In addition, control centers can be connected using various telecontrol protocols.

The CP is characterized by the following:

• Ethernet-based connection to TeleControl Server Basic, e.g. via Internet
• Ethernet-based connection to the control center via IEC 60870-5-104 or DNP3 protocol
• Data transfer of measured values, control variable values or alarms optimized for telecontrol systems
• Automatic sending of alert e-mails
• Data buffering of up to 100,000 values ensures a secure database, even with temporary connection failures
• Clearly laid out LED signaling for fast and easy diagnostics
• Fast commissioning thanks to easy configuration using STEP 7

The module can also be used for integrating the ET 200SP Distributed Controller into an IPv6-based network. All functions are configured using STEP 7 Professional V14 (TIA Portal) or higher.

The CP 1542SP-1 IRC supports the following communication services:

• Support of multiple telecontrol protocols such as DNP3, IEC 60870-5-104 and TeleControl Basic
• PG/OP communication
• S7 communication
• Open communication (Open User Communication)
• IT communication
  • Sending e-mails via SMTP or SMTPS with "SMTP-Auth" for authentication on an e-mail server (also with IPv6)
  • E-mail transfer with addressing by program block
  • E-mail transfer via "Notifications" (alerts)

• Failure protection
  The CP 1542SP-1 IRC has a large buffer memory for several thousand data values. It is thus possible to ride through downtimes of the transmission line.
• Fully automatic time stamp
  For correct archiving of process data in the control system, all data frames are provided with a time stamp at their place of origin.
• Fast and flexible data communication
  Operators are quickly provided with alarms, statuses and values from the process, and they can intervene in the process control at any time by entering commands or setpoints.
• Simple, low-cost engineering
  The cyclic or event-driven transfer of measurements, setpoints or alarms can be implemented in just a few steps and without programming effort.
• Remote diagnostics
  Saves traveling and maintenance costs due to cost-effective remote programming, diagnostics, control and monitoring via the Internet
• Network separation for setting up identical machines with the same IP addresses
• Optimum maintenance support:
  • Simple diagnostics via the central Web server
  • Monitoring with IT network management tools (SNMPv1)
  • Module replacement without a PG
• Simple alerting by e-mail
• Investment protection thanks to simple integration of the ET 200SP Distributed Controller in existing networks with SIMATIC S7-300 / S7-400 via Industrial Ethernet using the CP 1542SP-1 IRC
• Accessibility of the ET 200SP Distributed Controller from an IPv6-basedinfrastructure

• Prevention of data loss, production disruptions or machine damage by protecting against unauthorized access to the SIMATIC ET200SP Distributed Controller and lower-level networks.
• Optimum support of maintenance due to
  • Simple diagnostics via the central Web server
  • Monitoring with IT network management tools (SNMP)
  • Module replacement without a PG
• Securing the system against unauthorized access with
  • Central access protection for any S7 station
  • Secure access to the central Web server
• Simple alerting by e-mail

With the CP 1542SP-1 IRC, the ET 200SP Distributed Controller can be used as a Remote Terminal Unit (substation) in telecontrol applications. Typical uses include the collection of measured values in widely distributed outdoor areas (level measurement for water tanks) or centralized opening and closing of valves (oil/gas transport in pipelines).

• Plants in water, wastewater or environmental sectors:
  • Irrigation systems
  • Drinking water supply
• Monitoring of power networks for consumption metering and cost control
  • District heating networks
  • Wind farms
• Plants in the oil and gas sector
  • Oilfield water injection
  • Pipelines
• Transportation systems
  • Ventilation control in tunnel systems
  • Traffic control
