Chapter 1 Windows NT

1 1.1 Precautions

Power Supply

Turning the power off before normal ending of Windows NT may damage the file system and important files. In the worst case, Windows NT cannot potentially be started.

Make certain to execute finish processing of Windows NT before turning the power off.

Also, make certain to supply the power that is always stable.

Detection of Abnormal Temperature

If the operating environment is not suitable, the inside temperature of the main unit may exceed the specified value, which potentially presents a hazard of a system fault due to equipment malfunction.

The C2/C3 monitors the CPU temperature through the RAS feature and generates an alarm in case the temperature exceeds a preset value (currently 55oC), to notify a trouble. It is strongly recommended that application systems incorporate a program that detects this alarm. The program should inform the operator about a trouble and stop the system till the cause for a temperature error is removed when it receives such notice.

See the XrasUserWindow Command in "RAS Support Software" in chapter 3 for a method to detect a temperature error by a specific application program.

2.3.1API

The API needed for an application to access an I/O module is mounted as DLL. The file name of DLL is "g3iolib.dll."

The API provides interfaces for data input and output, various initializations, module error information acquisition and other purposes.

2.3.2Service

The service manages startup function registration when interrupts from the application are generated. In case an I/O module specified for startup is interrupted, the user function registered in advance is executed. The service manages batch input/output data between the driver and application.

The parameters to specify operations by the batch input/output feature are stored in the registry. For the complete information, see "2.7 Batch Input/Output"

2.3.3Tool

The tool is a GUI tool that operates on Windows NT. Using this tool, the following settings can be executed and information can be displayed.

(1) Individual mapping

The tool sets the types of mounting slots and modules of the I/O modules. Specify mounting slots by a channel number, unit or a position inside a unit. Specify module types by selecting from X, Y, X+Y, iX, iY and iX+Y.

The set information will be stored in the registry and will be looked up when the driver starts up.

	2.3 Software Configuration
	Individual mapping information, which is specified once, can be cancelled and automatic
	mapping can be executed.
	(2) Display of result of automatic mapping
	In case individual mapping is not specified, the driver will execute automatic mapping	2
	when the system is started. The tool displays results of automatic mapping.
	(3) I/O bus mapping address change
	Addresses of a memory space to be used by the I/O bus can be changed.
	A change is not required in normal operations. A change is needed only if an address
	conflicts when a PC card is used.
	The following two addresses can be selected:
	A) 0xD0000-0xD7FFF (Default)
	B) 0xD8000-0xDFFFF
	(4) Setting I/O bus time-out diagnosis time
	An I/O bus time-out diagnosis time is set. If ACK is not returned within a preset time, a
	hardware error will be declared and subsequent I/O bus accesses will be disabled.
	A diagnosis time can be set between 4 s minimum and 60 s maximum in increments of
	4 s. Default is set at 32 s.
	The following settings can be executed by directly changing registry values using the
	registry editor:
	• Execute/non-execute on startup of module diagnosis
	Whether or not to diagnose faults of the I/O modules executed by the device driver
	should be executed beginning system startup can be specified.
	Key: DiagStart
	Value: 0 (Non-execute on start [default]) or 1 (Execute on start)
	If execution is not started on start, diagnosis can be started using the function
	"IobusSetDiag."
	• Module diagnosis time interval
	A time interval to execute the foregoing module diagnosis is specified.
	Key: DiagInterval
	Value: An integer larger than 0 (in seconds); default value 5
	• Number of retry sessions during module error detection
	The number of retries executed when an error occurs in module accessing is specified.
	The driver tries accessing for the specified number. If errors still continue, the status of
	the module is set to "error" and this module will be excluded in subsequent accessing.
	By increasing this value, the resistance to temporary module errors increases. However,
	the input/output speed will lower.
	Key: RetryCount
	Value: An integer larger than 0 (in cycles); default value 5

2.3.4G3 I/O Driver

A G3 I/O access driver that functions as an I/O driver of Windows NT. The driver processes data input/output from applications via API and initialize requests.

Operations of this driver are transparent to the application program.

Chapter 2 I/O Bus Support Software

2.4 Precautions on Use of This Software

This software implements the features provided by S3 and S2 designed exclusively for I/ O module control. The integrated controller basically differs from the so-called PLC in

2 hardware and software and an application system must be designed heeding to the following when constructing an application system.

2.4.1Specification Limitations and Cautions

•In case more than one controller are installed in the same basic unit, only one controller installed in Slot 0 can control the I/O modules.

•The interrupt response time may vary depending on the system environment (hardware and software configurations and other elements).

•Intervals of interrupts from modules that may generate interrupts such as CDDIs and intervals of timer interrupts by software must be designed taking the load of the entire system into consideration. If intervals are too short, the response performance of the entire system may be lowered.

•A feature equivalent to the fixed-time scan feature in S3 can be implemented using Win32API. The interval accuracy depends on the features and performance provided by Windows NT.

•Depending on how the priority is set by application, operation of this software may delay by operations of other Windows applications.

•If I/O module accessing causes a time-out, scan execution period by the service will delay.

2.4.2Programming Precautions

•Application programs are created as Win32 applications.

The application programs call functions supplied by this support software and access the I/O modules.

•Fixed-cycle interrupts can be implemented by using a feature provided by Win32API.

•In both floating scanning and fixed-time scanning, the control structure such as repeating has to be described by an application itself.

•The startup timing of application programs that use the features of this software is the same as in starting ordinary Win32 applications.

•Execution of a program without releasing the CPU will deteriorate the response of the entire system.

•Functions can be started up by interrupts such as CDDIs. These functions are executed as threads and a library (libcmt.lib) compatible to multithreads must be linked during coding.

For the complete information, see the API reference "IobusRegCallbackFunc."

•Function ending and data sending to an actual device of batch output functions in this support software are not synchronized. Data is stored by output operation of the service.

For the complete information, see "2.7 Batch Input/Output"

2.4 Precautions on Use of This Software

2.4.3Comparison with S2/S3

•The feature "In case one scan processing time exceeds a preset time in fixed-time

scanning, scanning will change to floating scan, but will reset to fixed-time scanning

when the processing time returns" in S2/S3 is not provided. If this processing is 2 needed, it must be processed by an application program.

•Modes corresponding to HALT, HOLD and DEBUG in mode control processing provided by S2/S3 are not available.

•Normally operated in a mode corresponding to RUN or RUN-F. The mode will change to the ERROR mode if a critical error occurs, stopping the access feature.

Whether normal operations correspond to RUN or RUN-F depends on coding of the application program.

•User data is initialized by data setting by an application program.

•A feature to latch user data in a power failure is not provided.

2.4.4Purchasing and Development Environment

•This software is authorized to be installed in one each application development machine and target machine only. The user is requested to kindly purchase this software for each of target machines in case more than one target machine are used.

•A C/C++ development environment for Windows NT, such as Visual C++ of Microsoft, needs be purchased in developing application programs.
