  • Ability to format a SIMATIC memory card from STEP 7
  • Ability to prevent copies from internal load memory to external load memory (SIMATIC memory card)
  • Ability to save trace job measurements to external load memory (SMC)  - Persistent storage of measurements
  • Maximum size of 256KB for unlinked (load memory) data blocks, regardless of CPU model

  • Addtional programming instructions, e.g.:
  • GetInstanceName - Read out name of the block instance
  • D_ACT_DP - Enable/disable PROFINET IO devices
  • PROFIenergy - instructions for energy management
  • Gen_UsrMsg - Generate user diagnostic alarms
  •  CTRL_PTO - Pulse Train Output
  • Data block instructions:
  • DataLogClear - empty data log
  • DataLogDelete - delete dat log
  • CREATE_DB - create data blog
  • ATTR_DB - read data block attribute
  • DELETE_DB  - delete data bloc 

  • Web server enhancements
  • New or improved standard Web page
  • Watch tables - ability to display in engineering system configured watch tables
  • Online backup - easy ability to backup or restore running projects
  • Communication - additional info about communication statistics
  • Program protection - For a quick overview of enabled/disabled security mechanisms  (Know how and Copy protection) in the CPU directly on-site
  • Ability to define user-defined Web page as start page
  • New technology features, e.g.:
  • Enable and disable the HSC with the Gate input
  • Axis control using the TM Pulse module
  • Variable PWM and variable frequencies output  at runtime

  • Addtional failsafe CPUs and support PROFIsafe protocol,see entry109739232

Necessary requirements for running the above modules and functionalities

To configure the SIMATIC S7-1200 CPUs version 4.2 and higher you require the Engineering System Step7 with version V14 and higher.

See entry 109740340 

For using the new features

Time synchronization within central rack between CPU and CM/CP

the use of CP firmware at least V 2.1.77 is needed for CP 1242-7 V2, CP 1243-7 LTE, CP 1243-8 IRC , CP 1243-1

The 3964R protocol support for point-to-point communication needs to use firmware version 2.2 at least for CM1241  - see SIOS entry 109741869.

Compatibility and necessary components

SIMATIC Memory Card

A SIMATIC Memory Card can be used optionally for expanding the CPU load memory, loading the application software or for executing a firmware update. 

Compatibility of the hardware and software

Existing SIMATIC S7-1200 CPUs V4 (Article No. 6ES721x-1xx40-0XB0) can be updated to the new CPU firmware 4.2.

An S7-1200 CPU with version 4.2 is replacement compatible with an S7-1200 and firmware version 4.0 and 4.1. This enables the use of an real existing CPU with firmware version 4.2 with an engineered V4.0 or V4.1 based on an existing TIA portal V13 or V13 Service Pack 1 project. The new firmware features can't used in that case.
