07 KR 91 R303: (same functions as R202)
The device has a 115/230 V AC power supply voltage. It provides a 24 V output voltage for the supply of its own digital inputs.
07 KR 91 R353: (same functions as R252)
The device has a 24 V DC power supply voltage. It is provided with an additional interface for connecting communication modules (e.g. 07 KP 90).
1. Main features
· 20 digital inputs
· 12 digital relay outputs
· 1 counting input for counting frequencies up to 10 kHz
· 1 CS31 system bus interface for system expansion.
· Serial interface COM1
-is set as a programming interface
-can be set as an ASCII interface for connecting peripheral devices (e.g. MMC devices)
· Real-time clock
· Detachable screw-type terminal blocks
· Lithium battery 07 LE 90 can be put into the battery compartment ito
-store and back up the user program in the RAM
-store and back-up data, which is additionally contained in the RAM, e.g. the status of flags
-back-up the time and date (real-time clock)
-Self-diagnosis of the basic unit
-Diagnosis of the CS31 system bus and the connected modules
2. Project planning/start-up
The following has to be observed for project planning and start-up:
· Programming is performed using AC31 programming software, which can be run on commercially available IBM-compatible PCs (see documentation for the programming system 907 PC 331)
· The processor processes the user program contained in the RAM. It is loaded into the RAM via the serial interface COM1 and can also be changed there. An additional save command is used to save the program in the Flash EPROM.
· Online program modification. The two existing RAMs allow a quick modification of the user program to be performed without interrupting the operation (see programming system 907 PC 331).
-Stand-alone basic unit
-Bus master basic unit and
-Slave basic unit
The basic unit is set to Stand-alone upon delivery. Changing the application mode is carried out in the following three steps:
1. Change the system constant KW 00,00 in the PLC, see chapter A7.3 (Appendix), System constants.
2. Save the user program in the Flash EPROM.
3. Activate new application mode by:
-calling up the menu item of Enable PLC mode in the ABB programming and test system, or
-performing a warm start or
-performing a cold start.
