Description (continued)
Option
PROFIBUS DP Selects one of the following options:
Address— Changes the slave address
Data order— Sets the sequence of bytes when transmitting
floating point values. A floating point value consists of 4 bytes.
• Normal = IEEE Float Big Endian (Default setting)—The
pairs are not swapped. This mode fits to all known Profibus
master systems.
• Swapped = IEEE Float word wise swapped: Swaps the first
pair of bytes with the last pair.
SIMULATION Simulation— Simulates two floating point values and error/status
to substitute a real instrument. Select the following options and
use the arrows to enter the values or use the default setting:
• Simulation: Turns the simulation on or off.
Yes: Starts a simulation
No: Stops a simulation (Default setting)
• Period: Sets the time the first floating point value needs to
run through the whole range between MINIMUM and
MAXIMUM—2 min (Default setting)
• Maximum: Sets the upper limit for the first floating point
value.—20.0 (Default setting)
• Minimum: Sets the lower limit for the first floating point
value —10.0 (Default setting)
• Error: The value entered in this menu will be set in the first
simulated tag—16 (Default setting)
• Status: The value entered in this menu will be set in the
second simulated tag—5 (Default setting)
• Toggle: Changes the direction of the simulated ramp.
• Test/maint:
Enabled: Sets the TEST/MAINT bit (0x0004) of every status
register of every configured slave in the cyclic Profibus
telegram to indicate the "Service" mode.
Disabled: Normal operation mode (Default setting)
