 M Register Writing Range LO (PARAM36 and PARAM37)
These parameters set the lower limit of the allowable address range for write requests from the remote sta-
tion. An error will occur if the write request is outside this allowable range.
Specify the writing range with word addresses.
 M Register Writing Range HI (PARAM38 and PARAM39)
These parameters set the upper limit of the allowable address range for write requests from the remote sta-
tion. An error will occur if the write request is outside this allowable range.
Specify the writing range with word addresses.
Set the writing range so that it satisfies the following condition:
0 ≤ M register writing range LO ≤ M register writing range HI ≤ Maximum M register address
 G Register Writing Range LO (PARAM40 and PARAM41)
These parameters set the lower limit of the allowable address range for write requests from the remote sta-
tion. An error will occur if the write request is outside this allowable range.
Specify the writing range with word addresses.
 G Register Writing Range HI (PARAM42 and PARAM43)
These parameters set the upper limit of the allowable address range for write requests from the remote sta-
tion. An error will occur if the write request is outside this allowable range.
Specify the writing range with word addresses.
Set the writing range so that it satisfies the following condition:
0 ≤ G register writing range LO ≤ G register writing range HI ≤ Maximum G register address
 O Register Writing Range LO (PARAM44 and PARAM45)
These parameters set the lower limit of the allowable address range for write requests from the remote sta-
tion. An error will occur if the write request is outside this allowable range.
Specify the writing range with word addresses.
Use the following settings to set the allowable writing range of M register addresses to
MW0001000 to MW0001999:
PARAM36 = 03E8 hex (1000)
PARAM37 = 0000 hex (0000)
PARAM38 = 07CF hex (1999)
PARAM39 = 0000 hex (0000)
The MP3000 will return an error if a write request is received for addresses outside the range from
MW01000 to MW01999, and will not perform the writing operation.
Use the following settings to set the allowable writing range of G register addresses to
120000 to 136000:
PARAM40 = D4C0 hex (lower word for 120000)
PARAM42 = 0001 hex (upper word for 120000)
PARAM41 = 1340 hex (lower word for 136000)
PARAM43 = 0002 hex (upper word for 136000)
The MP3000 will return an error if a write request is received for an address outside the range from
GW0120000 to GW0136000, and will not perform the writing operation.
