OP2 is powered-up by switching-on the +24V power supply voltage. All of
the connections must be correct to ensure perfect functioning of the unit:
• USS connecting cable to SIMADYN D
• printer cable (if a printer is connected).
• power supply cable
After being powered-up, the „
approximately 5 seconds (the actual firmware version is displayed).
OP2 then goes into an automatic hardware test routine. The following
messages occur one after the another during this test routine:
EPROM ok Error
RAM ok Error
FLASH-TEST Error
Error
Error
TEST ok
The OP2 then automatically establishes a communications link to SIMADYN
D.
After a successful self-test, OP2 establishes a communications link to the
SIMADYN D subracks.
This procedure can either be initiated by SIMADYN D or by the OP2. This is
realized as follows
• SIMADYN D: After resetting or powering-up the subrack power supply.
• OP2: After powering-up the OP2 power supply voltage or, optionally,
when exiting the SYSTEM mode (for menu item „INIT REQUEST" in the
main menu „END").
When OP2 starts to establish the link, the following message is displayed
„INITIALIZATION REQUESTED" (upper display line). After the first data
have been exchanged with SIMADYN D, the process values are
automatically initialized (message in the lower display line: „PROCESS
DATA INITIALIZATION") and then the binary value initialization (message in
the lower display line: „BINARY VALUE INITIALIZATION").
