mbusm exccond e
*This is command is used when CTM200 is being used as a MODBUS Master*
Set the condition that will trigger MODBUS exception reports.
e = 0 Disable the MODBUS exception reports (default)
e = 1 to 7FFF in hex MODBUS events and exceptions to be used
MODBUS Event and Exception Bitmap:
bit0
Illegal Function Exception, Code 1 A master sends a Modbus function,
which is not supported by the slave device.
bit1
Illegal Address Exception, Code 2 A master queries an invalid or
non-existing data address.
bit2
Illegal Value Exception, Code 3 A master sends a data value, which is
not an allowable value for the slave device.
bit3
Slave Failure Exception, Code 4 An unrecoverable error occurs in the
slave device. The length might exceed the allowable data size.
bit4
Acknowledge Exception, Code 5 A long duration of time will be required
to process the request. This is to prevent a timeout error.

unable to establish a connection with the target device.
bit9

properly set.
bit12
Device Open Error Event, Code 14/0x0E The Modbus Master couldn't
open a serial or TCP slave device. The network is down, or the serial port
is already opened. The function code in $PMEX will be 0 for this event.
bit13
TCPIP Connection Closed Event, Code 15/0x0F TCP/IP connection was
closed by the remote slave device.
