MEDIA 0:Serial, 1:TCP/IP Serial Define Modbus channel type.
MASTER_SLAVE 0:Master, 1:Slave Slave Define if DFI is master or slave.
DEVICE_ADDRESS 0-247 1 Define the DFI Modbus address (only for DFI slave).
BAUD_RATE
0:110, 1:300, 2:600, 3:1200,
4:2400, 5:4800, 6:9600,
7:19200, 8:38400, 9:57600,

19200 Define the baud rate (only for media serial).
STOP_BITS 0:1, 1:2 1 Define the number of stop bits (only for media serial).
PARITY 0:None, 1:Even, 2:Odd. Even Define the parity (only for media serial).
TIMEOUT 0-65535 1000
Time to wait a response from a slave (for DFI master) or time to wait
the OUTs be updated (for DFI slave). Value 0 is used to disable.
NUMBER_RETRANSMISSIONS 0-255 1 Number of retransmission if DFI doesn’t receive response from slave.
SLAVE_ADDRESSES
IP number and Modbus addresses of slaves ( only for DFI master in
TCP/IP media);
RESTART_MODBUS FALSE
Indicate if after communication fail in the slave, there will be a new
transmission after the time defined in TIME_T
O_ RESTART (only for
DFI master).
TIME_T O_ RESTART 1-65535 1 Time to restart communication with slave
RTS_CTS FALSE Enable or disable handshaking.
ON_APPLY 0:None, 1: Apply None Apply the changes made in the Modbus blocks.
UPDATE_EVT This alert is generated by any change to the static data.
BLOCK_ALM
The block alarm is used for all configuration, hardware, connection
failure or system problems in the block. The cause of the alert is
displayed in the subcode field. The first alert to become active will set
the Active status in the Status attribute. As soon as the Unreported
status is cleared by the alert reporting task, another block alert may
be reported without clearing the Active status, if the subcode has
changed.
When using the RS-232, install the DF58 module (RS-232/RS-485 Interface Module) if it is
necessary to communicate with more than one Modbus instrument, that is, in a Multipoint Network.
Refer to chapter “Adding Interfaces”.
3) Now, create the other blocks. The Modbus available blocks are: MBSS (Modbus Supervision
Slave), MBSM (Modbus Supervision Master), MBCS (Modbus Control Slave) and MBCM
(Modbus Control Master).
