SCADAPack 32 Controllers Firmware Changes

The following changes are made to these controllers firmware:

  • Scanning of DNP points for change event is optimized to ensure change event processing does not affect TelePACE or ISaGRAF applications.
  • A check is added for all received DNP messages when a message transaction is currently active. When an incoming message has a different application sequence number from a currently active transaction it is queued. The new message is not part of the current transaction and is processed once the current transaction is complete.
  • A delay is added in the DNP slave operation to prevent new unsolicited messages from being initiated for a short period after receiving messages. Often a DNP master will send a sequence of messages in quick succession - for example during a poll sequence, or clock synchronization. Communication performance is improved by preventing unsolicited messages from being generated during these sequences thus reducing the probability of message collisions.
  • Message handling is improved to ensure unexpected messages received on a DNP communication port are rejected.
  • The DNP master polling operation is improved to ensure the last master message status is used when determining if a failure in communication with a slave station has occurred.
  • The DNP mimic mode operation is improved to ensure confirm messages are correctly relayed.
  • DNP routing is corrected to ensure messages sent on an RS-485 network are not interpreted as received messages and retransmitted.
  • The DNP master polling is corrected to ensure memory is allocated for all class data. The master would not allocate memory until a class 0 poll response was processed.
  • The DNP Write Analog Output Block message correctly updates the DNP master's data image.
  • DNP/TCP communication improved to ensure sockets are correctly closed.
  • DNP master communication corrected to ensure frames of 292 characters are correctly handled in multi-frame DNP/TCP and DNP/UDP messages.

Firmware Upgrade Procedure

Note: All application programs and data associated with the application programs are lost when the firmware is upgraded.
If you are planning to upgrade the firmware in your SCADAPack 32 controller to take advantage of the features and changes described above, it is recommended that the following steps be used. If you have any questions or concerns regarding this procedure contact Control Microsystems Technical Support using the information in the footer of this document.

1. Obtain Firmware Loader 1.42

Send an email to INFOCenter@controlmicrosystems.com. You will be contacted with the information you need to obtain this release.

2. Save your Current Application

Installing new firmware in a controller completely removes any application programs that may be running in the controller.
If you do not have a copy of the application program running in the target controller you will need to read the application from the controller before installing new firmware.

Note: C and C++ programs cannot be read from a controller. You must have a copy of the program before installing new firmware.
