1.4.1. Windows Specific Information¶
The windows runtime runs on NT..XP systems. There are the following derivates:
CODESYS Control Win V3: soft real time behavior
CODESYS Control RTE V3: hard real time behavior
CODESYS Simulation: runtime system for the simulation feature of CODESYS (soft real time behavior)
CODESYS HMI: runtime system without I/O handling, for the purpose of running visualization applications on external devices
Also the Gateway consists of runtime system components:
CODESYS Gateway V3: runtime system with gateway server functionality
1.4.1.1. Windows runtime services¶
The following windows runtime systems run as a windows service. They have all a command interface with the following calling options:
-i: |
Service gets installed |
|---|---|
-l: |
Specification of the Windows user account (add the username), under which the service should be started (only together with option –i) |
-p: |
Password of the Windows user (only together with –i) |
-u: |
Service gets de-installed |
-s: [<CODESYSControl.cfg>]: |
Service gets started. A cfg-file can be specified optional. |
-e: |
Service gets terminated |
-d: |
Service gets started as application in the console mode (running in a DOS box) |
-r: |
Debugging of the service without console window |
–startmode=auto: |
Service gets started automatically by Windows |
–startmode=demand: |
Service can be started manually under Windows |
CODESYS Control Win V3 (soft real time)¶
Windows soft real time runtime system (product name: CODESYS Control Win V3) based on a Windows service that is running with REALTIME process priority in user mode. All hardware access routines are handled by a kernel driver called SysDrv3S.sys. This driver must be installed for each (PCI) card that is plugged into the PC and wants to be used by the runtime system.
CODESYS Gateway Service V3¶
After a CODESYS standard installation, at system start the Gateway Server will be started automatically as a service. In addition and also automatically a separate application (GatewaySysTray) will be started, providing the gateway symbol in the system tray and – to be opened via this symbol – the gateway menu.
or running:
The gateway menu contains commands for explicit starting and stopping the gateway service as well as command „Exit Gateway Control” for terminating the GatewaySysTray application (not however the gateway service !). The GatewaySysTray application also might be started via the Programs menu.
The start mode for the gateway can be set in the Windows service manager or via a call option (see above: call options).
Note: The Windows firewall should be deactivated for the gateway systray application. The Windows firewall should be deactivated for the gateway systray application.
CODESYS Service Control V3¶
As authorization for starting/stopping services is strictly limited by Windows Vista, from CODESYS Version V3.2 SP1 Patch 2 onwards the services of CODESYS Control Win V3 and CODESYS Gateway Service V3 will be controlled by CODESYS Service Control V3.
Brand labeling¶
The default names of the services controlled by CODESYS Service Control V3 may be modified by editing the following resources:
ServiceControl.exe:
ID 3: vendor name (used for shared memory name!)
ID 4: name of the CODESYS Control service
ID 5: name of the Gateway service
GatewaySysTray.exe:
ID 8: vendor name (used for shared memory name!)
ID 9: name of the Gateway service
CODESYSControlSysTray.exe:
ID 8: vendor name (used for shared memory name!)
ID 9: name of the CODESYSControl service
1.4.1.2. CODESYS Control RTE V3 (hard realtime)¶
Windows hard real time runtime system (product name: CODESYS Control RTE V3) operating with an own scheduler that runs windows as an idle task. All other real time tasks are executed before Windows. A special time-slicing mechanism distributes the process consumption in a fix quota between the plc tasks and the windows operating system. This quota can be for example 70% plc and 30% windows.
1.4.1.3. CODESYS integrated runtime systems¶
CODESYS simulation¶
Windows soft real time runtime system integrated in CODESYS, used for the simulation feature.
CODESYS HMI¶
Windows soft real time runtime system (product name: CODESYS HMI) which corresponds to the CODESYS Control Win V3 runtime system, however with deactivated I/O-handling functions. Serves to run a visualization application on a corresponding device (standard device: CODESYS HMI for Win32).
