4.2 Instructions on installing the CPU 486-3
•The hardware version of the CPU 486-3 must be at least 2. Earlier versions can cause serious errors in the functions that use an interface module.
•When using the TPM 478 with a CPU 486-3, the CPU BIOS must be at least version V2.07. This is guaranteed if hardware version 2 of the CPU 486-3 is used.
•When installing the new CPU 486-3 modules, the red INTF LED can illuminate for several seconds during booting. This indicates that the BIOS has found a configuration that does not agree with the last one saved. To stop this procedure, the data with the configuration found by the BIOS when booting up must be saved. This can be achieved when operating the machine for the first time in the following way (for further information please refer to the SIMATIC S7 module manual):
a)Connect the terminal / hyper-terminal program to the COM1 port of the BRIDGE CS- L2.
b)During booting of the BRIDGE CS-L2, press the Q key until the BIOS comes up.
c)Select the window with the system parameters
d)Leave the window with the system parameters, without making any changes.
e)Leave the BIOS setup with the SAVE option. This creates, among other things, a new checksum of the BIOS data, the checksum is then saved in the module.
f)When the system is booted up in future, the INTF LED will not illuminate unless there is a further CPU error.
•When booting up the Bridge CS-L2, the BIOS start-up of the CPU 486-3 lasts about 10 seconds. A criterion for this is that only the red STOP LED of the CPU 486-3 is lit. When the operating system RMOS32 and the bridge system software are then subsequently loaded, the green SD LED flashes or is lit continuously. If there is a significant delay before the green SD LED illuminates, the BIOS settings can be changed to reduce the BIOS start-up time. The following settings in particular should be implemented (for further information please refer to the SIMATIC S7 - module manual /1/):
♦ SETUP page „Hard Disk“: | Switch off ‘Auto’ option |
♦ SETUP page „Floppy/Card“: | Set drive A to MemCard |
•With the BRIDGE CS-L2, the module slots on the CPU 486-3 must not be fitted with an IF964 interface module. An IF964 module inserted here cannot be addressed by the BRIDGE CS-L2 system software.
