MODCELL SERIAL COMMUNICATION BLOCK
4-30
41
Scan Buffer Full Counter (QFULLC)..............................................................................– WR
Each of the above diagnostics has a counter which is a free running count (0 to 65535) of the
quantity of errors detected. The count is active even if the diagnostic is suppressed.
44
Mode (MODE)..................................................................................................................... – – R
The Modbus transmission mode of this block. Currently the only valid value is RTU. This
value is read as 0.
45 Modcell Serial Address (ADDR)....................................................................................... CWR
This value represents the address (1 to 247) for this Modcell Serial communication module.
For those modules with an address switch, the instrument checks that the switch setting
matches the number entered here, or ANY tells instrument to accept any setting. Enter 1-247
(or ANY for modules with an address switch).
46 Baud Rate (BAUDRATE) ................................................................................................... CWR
This value represents the communications port data rate (baud rate). Valid values are:
150 0 Data rate is set to 150 baud.
300 1 Data rate is set to 300 baud.
600 2 Data rate is set to 600 baud.
1200 3 Data rate is set to 1200 baud.
2400 4 Data rate is set to 2400 baud.
4800 5 Data rate is set to 4800 baud.
9600 6 Data rate is set to 9600 baud.
19200 7 Data rate is set to 19200 baud.
38400 8 Data rate is set to 38400 baud.
47
Data Bits (DATABITS)........................................................................................................ – – R
This value represents the number of data bits in the communication data. Currently, the only
valid value is 8 (for RTU mode).
48 Parity (PARITY).................................................................................................................. CWR
This value specifies the parity bit representation.
NONE 0 No parity.
ODD 1 Odd parity.
EVEN 2 Even parity
49 Stop Bits (STOPBITS) ....................................................................................................... CWR
This value represents the number of stop bits in the data. Valid values are 1 and 2.
