KEPServerEX 5.10.205.0

Server Runtime

• Added the new channel-level System Tags "_SharedConnection" and "_CommunicationSerialization._TransactionsPerCycle".Eliminated Property Tags from System Tags for consistency with 4.x. This also reduces memory consumption when a client browses a server address space that contains a large number of devices.

• Prevented the server from loading drivers and plug-ins that fail digital signature verification.

• Fixed an issue where the Key Service failed to start, resulting in an "Invalid or missing user information" message.

Configuration

• Updated the user interface to support Connection Sharing.

◦ Added a new view to show the list of channels.

◦ Added a user-selectable organizational view of the Project Tree (by driver or connection).

◦ Added access to the Driver Summary information from the driver organizational view.

◦ Added an item to the Driver Summary information that indicates whether the driver supports Connection Sharing.

◦ Provided drag and drop configuration for Connection Sharing project setup.

• Changed the Communication Diagnostics view's color scheme to a grey background for RX and to green text for TX. The text and background color of TX and RX events is always set, so coloring will be consistent even on systems that have custom window colorings defined.

Install

• Added the Connection Sharing Plug-In. It is selected for installation by default.

• Added the ABB Totalflow Driver. It can be selected for installation independently or as part of the Oil & Gas product bundle.

New!

Initial release of the new driver with support for real-time and EFM communications. This release provides support for connectivity to Totalflow devices using the native DB2 protocol. The driver is a serial driver but supports Ethernet Encapsulation. The driver can be selected for installation independently or as part of the Oil & Gas Suite.

Updates

• Added support for a new service introduced in Logix FRN V21 for reading Native Tags, called Symbol Instance Addressing. Physical addressing has been deprecated for V21 but is still supported in the driver for Logix FRN V20 and below. Replaced Physical Non-Blocking and Physical Blocking with Logical Non-Blocking and Logical Blocking to encapsulate these two services.

• Improved the demotion of tags while in an error state by increasing the number of tags failed per transaction. The driver still attempts at least one read tag per transaction to recover from the error state. This does not apply when Auto Demotion is enabled.

• Fixed an issue where project correlation state information was not being properly reset when switching from one device connection to another which could result in that device using Symbolic mode indefinitely.

• Resolved a buffer overrun issue where the Device ID could become corrupt if the length of the portion preceding the comma exceeded 16 characters.

• Added an address validation check to ensure a tag's Symbolic address fits within a single CIP packet. If it exceeds a single packet, the tag will fail with "Address out of range".

• Floats and Doubles written to BOOL, SINT, INT, DINT, and LINT Tags are now clamped in order to prevent roll-over. For example, the Float 4294967395.0 is larger than a DWord (4294967295) and would roll-over to 0. With this fix, 4294967395.0 will be clamped to 4294967295.

• Fixed an issue that occurred when writing to BOOL and SINT Tags for Serial Gateway models.

Communication Serialization

Added support for Communication Serialization.

OPC Read Only

Fixed an issue that was introduced in the 5.3 release when compatibility information was added that affected the reading of OPC Read Only variables.

Updates

• Changed the Data Link Layer Confirmation Timeout from 2 seconds to the configurable Channel Response Timeout.

• Fixed an issue where collected events did not continue to playback when the device was in an error state.

◦ Tag quality will be Bad if the device error state continues after playback completes.

◦ During device demotion, tags will have Bad Quality and no playback. After the device is promoted, tag quality will be Good and playback will continue.

• Fixed an issue where collected events were incorrectly deleted from the driver's cache after specific communication failures. Resolved an issue where the Auto-Demotion settings in device properties were not used on startup.

• Enhanced the driver to consume the extra bytes that may be received following a valid frame.

Updates

• Added Electronic Flow Measurement (EFM).

• Support Updated the driver with the new Connection Sharing feature.

• Added a device setting to enable/disable sending a device login password.

• When transactions fail due to an Operator ID failure, a single custom error message will now be posted per device.

• Enhanced the driver to consume the extra bytes that may be received following a valid frame. This allows communication with ROC 300 devices, which may append an extra byte to every frame they transmit.

Communication Serialization

Added support for Communication Serialization.

Updates

• Fixed data conversion for BCD and LBCD arrays.

• Resolved an issue where the driver was not locking a process thread correctly, which could cause the driver to stop issuing polls to devices.

• Fixed a data alignment issue that occurred when reading and writing symbolic discrete array variables.

◦ Symbolic discrete array element tags require two symbolic information requests in order to calculate the start byte based on the base array address and the array index.

◦ Recalculate the native data size of symbolic discrete array and array elements depending on data type.

◦ Fail request and report warning message occur if the symbolic discrete array native data size exceeds the maximum request size (because it cannot be caught in the address parser).

◦ Corrected a pre-existing issue in the tag import to force the "{" on array element tag addresses.

◦ Handle nested symbolic discrete array variables.

◦ Clear previously collected symbol information after an invalid PVT version.

Address Types

Performance enhancement for Address Types X, Y, and C.

Set (Write)

Fixed an issue with Set (Write) operations where the driver would not always encode integer values in the smallest possible number of octets. For certain managed devices, this could cause the Set operation to fail.

Custom Checksum

Added the new custom checksum "Custom #14 (8-bit)". The check sum is determined by subtracting the valid hex numbers and the ASCII values of non-valid hex numbers from 0x00, and then swapping the Hi and Low nibbles.

Connection Sharing

Updated the driver with the new Connection Sharing feature.

Timeout

Added a new state to ensure that request timeout error messages are only logged once between the acquisition of data.

Enable Data Collection

Fixed an issue where unchecking the Enable Data Collection option while clients were connected could result in a deadlock.
