Installation
3.10.2 sc1000 controller software settings
The Modbus TCP software module is configured in the following sc1000 controller
menus:
SYSTEM SETUP
MODBUS TCP
MODBUS TCP Determines whether Modbus TCP is activated (ON) or not (OFF).
TCP PORT Determines the TCP port.
TELEGRAM Configures a slave based on individual data compilations from various devices.
MODBUS ADDRESS
Default value: 0
Determines the address (1 to 247) of the Modbus slave configured in the TELEGRAM menu.
VIRTUAL SLAVES
Default value: DEACTIVATED
Virtual slaves can be added. These are copies of actual devices and are configured in the
TELEGRAM menu. The Modbus addresses for these slaves are displayed directly to the right of
the configured slave's address. The Modbus address of the first configured device is displayed
directly to the right of the configured slave's address, the address of the second device is
displayed to the right of that, and so forth.
ACTIVATED: Slave copy is activated.
DEACTIVATED: Slave copy is deactivated.
DATA ORDER
Default value: NORMAL
Determines the byte sequence for transferring floating point values. A floating point value
consists of 4 bytes.
Note that this setting only relates to data of the configured slave.
SWAPPED: Swaps the first byte pair with the last byte pair.
NORMAL: The pairs are not swapped.
An incorrect setting in this menu can lead to slight deviations in the floating point values (shifted
by one register).
SIMULATION
Simulates two floating point values and errors/statuses to substitute an instrument. The first
floating point value passes through a ramp between limits set in the MINIMUM and MAXIMUM
menus.
SIMULATION
Default value: NO
Switches simulation on (YES) or off (NO).
DURATION
Default value: 10 minutes
Determines the time required by the first floating point value to pass through the entire range
between MINIMUM and MAXIMUM.
MAXIMUM
Default value: 100
Upper limit for first floating point value.
MINIMUM
Default value: 50
Lower limit for first floating point value.
ERRORS
Default value: 0
The value entered in this menu is set as the value in the first simulated register.
STATUS
Default value: 0
The value entered in this menu is set as the value in the second simulated register.
TOGGLE Changes the direction of the simulated ramp application.
STATUS Contains information for data transfer.
