a) Device ID Register: This field is for configuring Node ID of the Profibus slave,
any word accessible register type can be configured.
Node ID ranges from 1 to 125. If Slave ID is out off range (i.e. less than 1
or greater than 125) Profibus status will be 0xFEFE.
There are 2 methods for setting slave ID:
Method 1: Slave ID can be set through a logic register. If the ID is
changed in the register via ladder, unit needs to be put
through RUN-IDLE-RUN mode for this new ID to take effect.
Method 2: Slave ID can be directly set (value set between range 1
through 125). If the ID is changed then a new configuration
needs to be downloaded and unit power cycled for config to
take effect.
b) Bit Input Table:
Start Register: This field is for configuring Input byte data type of Profibus
communication, any bit accessible register type can be configured.
Length: In this field user has to define a value in terms of number of bits.
Example: For 232 byte data exchange, configure length as 1856 bits = 8 *
232.
c) Word Input Table:
Start Register: This field is for configuring Input word data type of Profibus
communication, any word accessible register type can be configured.
Length: In this field user has to define a value in terms of number of words
d) Bit Output Table:
Start Register: This field is for configuring Output byte data type of Profibus
communication, any bit accessible register type can be configured.
Length: In this field user has to define a value in terms of number of bits.
Example: For 1 byte data exchange, configure length as 8 bits.
e) Word Output Table:
Start Register: This field is for configuring Output word data type of Profibus
communication, any word accessible register type can be configured.
Length: In this field user has to define a value in terms of number of words.
3. Status (Read only):
This field is for configuring status word, any word accessible register type of OCS
can be configured. Table below describes the status word:
Examples:
a) If Profibus master is configured for 1.50Mbits/s and communicating with profibus
slave, the status register will be 0xD3A1.
D = chip release information (refer status information table)
3 = baud rate information
A = slave is in data exchange mode
1 = slave is in passive idle mode
b) If Profibus master is not communicating with slave, status register will be 0xD341
4. Firmware version:
This field is for configuring Profibus option module firmware version number, any
word accessible register type of OCS can be configured for this.
Example:
If the selected register is %R1 and the firmware version is 0.02, then
0.02*100 = 2 will be displayed.
NOTE: Power cycle of the device is needed for every new configuration
download to slave device for this configuration to be active.
5 Installation / safety
When found on the product, the following symbols specify
Warning: Consult
Warning: Electrical
Shock Hazard.
WARNING: To avoid the risk of electric shock or burns, always connect the
safety (or earth) ground before making any other connections.
WARNING: To reduce the risk of fire, electrical shock, or physical injury it is
strongly recommended to fuse the voltage measurement inputs. Be sure to
locate fuses as close to the source as possible.
WARNING: Replace fuse with the same type and rating to provide protection
against risk of fire and shock hazards.
WARNING: In the event of repeated failure, do not replace the fuse again as
a repeated failure indicates a defective condition that will not clear by
replacing the fuse.
WARNING: Only qualified electrical personnel familiar with the construction
and operation of this equipment and the hazards involved should install,
adjust, operate, or service this equipment. Read and understand this
manual and other applicable manuals in their entirety before proceeding.
Failure to observe this precaution could result in severe bodily i
of life.
