Error/Status Block Pointer
1 to 7000
The Error/Status Block Pointer parameter is used to specify the range of
database registers to use for error and status data. The value should be no lower
than 700, to avoid overwriting data, and no higher than 6970, to allow sufficient
space for the error/status block.
6.2.3 [MCM Port X]
The information in this section applies to both Port 1 and Port 2.
# This section is used to define the port 1 configuration for the MCM device
#
[MCM Port 1]
Enable : Yes #No=Port Disabled,Yes=Port Enabled
Type : 5 #Type of port (0=Master, 1=Slave, 2=Block PT,
#3=Block PT Swap, 4=Direct PT, 5=Direct PT
Swap)
Pass Thru Address : 300 #Address where pass-thru block id is used only
#Type equal to 2 or 3
Float Flag : No #Float Flag (No=No Floating Point Data,
#Yes=Use Floating Point Data)
Float Start : 4000 #The first register of floating-point data.
Float Offset : 2000 #Internal DB offset to start of floating point
#data
Protocol : r #ASCII or RTU
Baud Rate : 192 #Baud rate for port (300, 600, 1200, 2400,
4800,
#9600, 19200, 38400, 57600, 115(for 115200))
Parity : None #N=None,O=Odd,E=Even
Data Bits : 8 #7 or 8 data bits for messages
Stop Bits : 1 #1 or 2 stop bits for messages
RTS On : 0 #Delay after RTS set before message sent (mSec)
RTS Off : 0 #Delay after message before RTS dropped (mSec)
Minimum Response Delay : 0 #Number of mSec to delay before response
Use CTS Line : No #Monitor CTS modem line (Y/N)
Slave Address : 1 #0-255 Slave Node Address
Bit Input Offset : 0 #Internal DB offset to bit input data (Slave)
Word Input Offset : 0 #Internal DB offset to word input data (Slave)
Output Offset : 0 #Internal DB offset to bit output data (Slave)
Hold Offset : 0 #Internal DB offset to bit output data (Slave)
Command Count : 3 #Command list count (Master)
Min Cmd Delay : 1 #Minimum time between each command
#(Master 0-65535)
Cmd Err Pointer : 4500 #Internal DB location to place command error
#list (Master 0-4900)
Response Timeout : 0 #Response timeout for command (Master)
Retry Count : 2 #Retry count for failed request (Master)
Error Delay Count : 0 #Command cycle count if error (Master)
Enable
Enable : Yes #No=Port Disabled,Yes=Port Enabled
This parameter is used to define if this Modbus port will be used. If the parameter
is set to 0, the port is disabled. A value of 1 enables the port.
