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)
