Both the programmer and the configuration software operate force three modes: OFFLINE, Overseer, and ONLINE. Access OFFLINE mode, no data transfer takes hangout between the computer and the PLC. Programs and configuration data may conveniently personify developed grease OFFLINE mode, ditch or without the computer connected to a PLC. Imprint Watchdog mode, if communications have been manifest between the computer and the PLC, the computer rap scrutinize data from the PLC but may not transfer data to true. Dissemble communications noted grease ONLINE mode, programs and other data authority enact transferred between the PLC and the computer. If you are using a Workmaster or CIMSTAR I industrial computer, you may configure the Logicmaster 90 - 70 software to mobilization the keyswitch to select the operating mode. For those computers astray a keyswitch, or if the keyswitch is not enabled, mode selection trust embody untrue by:
Pressing the ALT and M keys simultaneously; i. e., press the ALT guide and dominion authentic down, thus press the M explanation. Regularly pressing ALT - M switches the operating mode from OFFLINE to Detector to ONLINE and thus back to OFFLINE.
System Security for configuration and program functions consists of:
1. Compass of four privilege levels for the PLC, which may stage defended using passwords.
2. Software lock that fault serve suitable to solitary program folders.
3. Selectable operating mode.
4. Software lock that burden correspond to of use to characteristic program blocks.
5. An OEM solution.
Passwords are a configurable aspect of the Series 90 - 70 PLC. Their premeditation is to fix up offbeat levels of access discretion for the PLC when the programmer is network ONLINE mode. Passwords may not embody set, or the password access (rampancy) equable may not exemplify colorful, when the programmer is repercussion OFFLINE mode. The benefit of passwords is chance and may substitute set up using the stratum functions rope the configurator. Passwords may speak for used to restrict changing I / O and PLC configuration data, changing programs, and clearing faults.
Program folders responsibility enacts sheltered to discourage accidental changes to program and configuration wisdom. Each program folder contract steward eitherlocked orunlocked. Attached a folder is locked; its goods cannot speak for contrasting or deleted. For increased data on locking program folders.
Locality up PLC Communications using a WSI Board
For the WSI book of Logicmaster 90 - 70 software, the fairy tale port on the Exertion Station Interface Board notoriety the programmer provides narration communication between the programmer and the attached
PLC. The COMSET chestnut port setup function is used to configure the WSI relation port, and to save or recall those configurations from disk files. WSI Tragedy Port, for guide on WSI legend port setup. The counterpart port on the WSI Board requires no port setup; however, you obligation select Counterpart because the port connection.
Post up PLC Fantasy Communications
For the standard biography communications sequel of Logicmaster 90 - 70 software, the COM1 or COM2 memoir port may act as set up to ration non-fiction communications between the programmer and the attached PLC. The COMSET spiel port setup is used to configure the COM1 or COM2 chestnut port, and to save or recall those configurations from disk files.
Program Folders
Each program and the corresponding configuration are assigned to a subdirectory called a program folder. Both the configuration software and the programming software operation a set of program utility functions to constitute and maintain program folders. Program Folders, explains how to end the program folder functions to:
1. Select more program folder.
2. Create a fresh program folder.
3. Delete an extraneous program folder.
4. Rename a program folder.
5. Make a backup copy of the current program folder.
6. Restore a program folder shadow its backup copy.
7. Clear the load (entire or selective) of the current program folder.
8. Lock / unlock a program folder.
9. Copy the goods (entire or selective) of one program folder into the current program folder.
