2.2.7 Pass-Through Events
Y or N (N = Default)
This parameter specifies if event messages received on the master ports will be
passed to the processor. If the parameter is set to N, event messages will not be
passed to the processor. If the parameter is set to Y, the module will pass all
events received to the processor using block identifier 9903.
2.2.8 Block Transfer Size
60, 120 or 240
This read-only parameter specifies the number of words in each block transferred
between the module and processor. Valid values for this parameter are 60, 120
and 240.
2.3 [IEC-870-5-103 Master]
2.3.1 Session Count
1 to 16
This parameter specifies the maximum number of sessions 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.
2.4 [IEC-870-5-103 Master Port x]
2.4.1 Baud Rate
Value for baud rate
This parameter specifies the baud rate to be used on the communication channel
(port). Two values are valid; 19200 or 9600.
2.4.2 Parity
N, O, E, M, or S
This parameter sets the parity to be used on the port. The values correspond to
the following settings: N=None, O=Odd, E=Even, M=Mark and S=Space.
Note: the specification only utilizes Even Parity.
2.4.3 RTS On
0 to 65535 milliseconds
This parameter sets the number of milliseconds to delay after RTS is asserted
before the data will be transmitted.
