[Section]/Item Value Range Description
Read Register Count: 0 to 4000 This parameter specifies the number of registers
to be transferred from the module to the
processor. Valid entry for this parameter is 0 to
4000.
Pass-Through Events: Yes or No This parameter specifies if event messages
received on the master ports will be passed to the
processor. If the parameter is set to No, event
messages will not be passed to the processor. If
the parameter is set to Yes, the module will pass
all events received to the processor using block
identifier 9903.
[Section]/Item Value Range Description
[IEC 60870-5-101
MASTER] Module level parameters
Session Count: 1 to 32 This parameter specifies the maximum number of
session to establish on the module. This
corresponds to the number of slaves to be
interfaced with the module. This value represents
the total number of slaves on both ports
combined.
[Section]/Item Value Range Description
[IEC 60870-5-101
MASTER PORT x] Settings for each communication port on module
Baud Rate: Value for
baud rate This parameter specifies the baud rate to be used
on the communication channel (port). Values from
110 to 38.4K are permitted.
Parity: None, Odd,
Even This parameter sets the parity to be used on the
port. The values correspond to the following
settings: None, Odd, Even.
RTS On: 0 to 65535 The parameter sets the RTS pre-send delay. The
value entered represents the number of
milliseconds the module will wait after setting the
RTS modem line before sending the data.
RTS Off: 1 to 65535 This parameter sets the RTS off delay. The value
entered represents the number of milliseconds the
module will wait after the data packet is sent
before dropping the RTS modem line.
Minimum Delay: 1 to 65535 This parameter specifies the minimum number of
milliseconds to delay before sending the message
(setting RTS high). This can be used when the
serial network requires time for units to turn off
their transmitters.
Receive Timeout: 1 to 65535 This value represents the number of milliseconds
to wait on a port from the time the first character is
received until the last character in the longest
message received on the port. This parameter
should be set dependent on the baud rate. A
value of 2000 should work with most applications.
Single char ACK F0,1 or
3: Yes or No This parameter specifies if the single E5 character
will be used for ACK messages.
