GJR5252300R0101 7AC91D ABB input module application

First, the block must be configured with a Hand-held Monitor to:
Enter its Device Number (serial bus address).
Enter its Reference Number (required only for IC600 and IC550 series PLCs only).
Enter its counter type (A, B, or C). Note: If a block is configured offline, it must be properly grounded and have a 75 Ohm resistor installed across its Serial 1 and Serial 2 terminals. See the High-speed Counter User’s Manual for instructions. The rest of the features can be configured either using a Hand-held Monitor, or by sending a Write Configuration datagram to the block from the host. Note: If the counter is operating at a count rate of 150KHz or higher, run-time configuration changes should be made using a Hand-held Monitor. F

Project planning / start-up 

The following has to be observed for project planning and start-up: • Programming is performed with AC31 programming software, which can be run on commercially available IBM compatible PCs (see documentation of the programming system 907 AC 1131). • Online program modification A quick modification of the user program is possible without interrupting the operation (see programming system 907 AC 1131). • Possible operating modes – Stand-alone basic unit – Bus master basic unit – Slave basic unit • Backup of data areas, i.e. saving of data during power OFF/ON, is possible with an integrated battery and/or by storing them in the Flash EPROM. • When using the PROFIBUS DP interface, project planning is performed in the same way as with 07 KT 97. For details see chapter "System Description

• Real-time clock

 • LEDs for displaying operating conditions and error messages 

• Detachable screw-type terminal blocks

 • Fastening by screws or by snapping the device onto a DIN rail 

• The lithium battery 07 LE 90 can be put into the battery compartment in order to – store and backup data which is additionally contained in the RAM, e.g. the status of flags (RETAIN) – backup the time and date (real-time clock) 

• RUN/STOP switch for starting and aborting the program execution 

• Extensive diagnosis functions – self-diagnosis of the basic unit – diagnosis of the CS31 system bus and the connected modules
