Rockwell recently released version 20 of Connected Components Workbench, and below I’ll summarize any new and enhanced features:

New and Enhanced Micro800 Features:

  • Micro800 L50E and L70E controllers are added to CCW
  • Added encryption of backup of memory module & SD card when backing up projects
  • Added support for DNP3 Slave protocol for 2080-L70E-24QWBN and 2080-L70E-24QBBN
  • Now supports Half-duplex Master, Half-duplex Slave, and Radio Modem modes for DF1 with L50E and L70E
  • The download and upload speed for Micro800 L50E and L70E controllers increased when connected via USB or Ethernet
  • Now supports filtering variables by multiple datatypes at one time

New PV800 Features:

  • Now supports highlighting objects using PanelView 800 tags in the Cross Reference of CCW software.
  • Alarm History size has been increased
  • L306 time-out parameters now supported

Functional Changes:

  • Change in controller password length

The length of controller passwords was changed from between 8–32 characters to between 1–64 characters.

If the password is less than 8 characters or more than 32 characters in CCCW v20.01, the controller cannot be connected to the older versions of CCW.

  • Change in operating system support

Starting in this release, the CCW installer will no longer install on 32-bit versions of Windows or any Windows 7 OS .

  1. CCW is horrible software. I have programmed hundreds of HMIs with this and I am giving up and going back to Automation Direct for our HMIs. I have lost hundreds of hours with this software. It doesn’t save a project well and I end up losing about 20% of my productivity when I save a program after 4 hours then reopen it to find that all of my recent work is gone!
