Improved: Extended the support for shortcut keys for editing variables in the Modbus Devices tab of the Configuration Mode UI. Improved: Added support for IPv6 addresses for OPC UA Endpoints Improved: SourceTimestamp of values in the OPC UA address space now reflects the time when the value was retrieved from the Modbus device
Improved: Improved support for features of the OPC UA MonitoredItem Service Set and Read Service in accessing Modbus data Improved: Major improvements in performance of accessing data from Modbus devices New: Device-wide setting for the default byte transfer order of new variables (swap bytes and swap words) New: New right-click menu commands for performing actions on Modbus devices, tables and variables in the Configuration Mode UI New: Option to use BIT data type for Input and Holding Registers.
#Modbus server vs application server 64 Bit
New data types include 8 bit and 64 bit integers (SINT, USINT, LINT, ULINT), 64 bit floating-point decimal (LREAL) and character strings encoded in ISO 8859-1 and UTF-16 (CHAR, WCHAR) New: Extended support for different IEC 61131-3 data types. New: Possibility to import and export device-specific variable configurations from/to a CSV file through the Configuration Mode UI
#Modbus server vs application server serial
New: Support for Modbus serial protocol (ASCII and RTU) If for some reasons it won’t work on your distro, let us know, but you can chmod the exec bits as a workaround. zip option uncompressed retaining exec bits on start scripts on Linux, which was the only reason keeping tar.gz.
#Modbus server vs application server portable
Not recommended for public networks.Ĭhanged: Removed portable tar.gz option, based on our latest tests the. They are considered to be non-secure by OPC UA 1.04, but can be enabled in the Endpoints view if needed. sh script (like our Browser/SimulationServer/Monitor have).Ĭhanged: MessageSecurityMode None is no longer enabled by default (unless migrated from old configuration file).Ĭhanged: SecurityPolicies Basic128Rsa15 and Basic256 are no longer enabled by default (unless migrated from old configuration file). New: Added support for reverse connections.įixed/Changed: Transport protocol opc.https disabled by default.įixed: UI could freeze if "Open Certificate in OS viewer" option was used on Linux.įixed: Application’s own Certificates can now be opened in the Certificates view.įixed: Selecting serial port based Modbus Device did freeze the application if run in portable mode.Ĭhanged: Linux installer is now a. New: Docker Image as distribution option. Uses Prosys OPC UA SDK for Java version 4.5.2: NOTE! for the "portable install" and docker distributions, there could be more impact if the user running the application differs from the one unzipping the distribution and/or if that user has higher privileges on the system.
#Modbus server vs application server update
Thus, this CVE in practice has no impact, but we still do recommend to update just in case. Thus the created configuration files at the first startup are admin-owned, thus there is nothing to escalate to, the attacker could just do already everything they could do via Modbus Server in a more complicated way. Typically this kind of vulnerability could be used for a privilege escalation attack, but Modbus Server for better or worse requires admin priviledges to run. In general our applications do not expect a hostile (local) environment. So the filesystem would have to be compromised for this to happen. This limitation must be taken into account when setting up the Block Settings of the TOP Server device - since Modbus is lower across the board there should not be any problems with JBus Devices.For the CVE-2021-44832, per apache’s page: "(previous versions) are vulnerable to a remote code execution (RCE) attack where an attacker with permission to modify the logging configuration file". Max number of words to be written in single request Max number of bits to be writen in single request Max number of words to be read in single request Max number of bits to be read in single request Modbus and JBus have different "limitations" when it comes to packet capacity.
The register offset of 1 can easily be configured in the device properties "Use zero based addressing" found under the Settings tab Modbus is natively a 0 based addressing protocol (Reg+1), whereas JBus is natively a 1 based addressing protocol (Reg+0).There are a few considerations that need to be taken into account:
#Modbus server vs application server driver
The two protocols are certainly compatible, and the TOP Server Modbus driver will be able to communicate with devices that speak either protocol. April develeoped their own version of Modbus later dubbed JBus. The Modbus Protocol was initially developed by Modicon.
