4. DESCRIPTION OF PARAMETERS
173
3441 First of the M codes assigned to item numbers 100 to 199
3442 First of the M codes assigned to item numbers 200 to 299
3443 First of the M codes assigned to item numbers 300 to 399
3444 First of the M codes assigned to item numbers 400 to 499
[Data type] 2–word
[Valid data range] 0 to 99999999
The M code group check function checks if a combination of up to three M
codes specified in a block is valid, and the function issues an alarm if an
invalid combination is detected. Before this function can be used, up to
500 M codes must be divided into no more than 128 groups. A set number
from 0 to 499 is assigned to each of the 500 M codes. The group to which
each M code with a set number assigned belongs is specified using the M
code group setting screen.
The set numbers 0 to 499 correspond to M000 to M499. These parameters
allow arbitrary M codes to be assigned in units of 100 M codes to the set
numbers 100 to 499.
Parameter No.3441: Sets the M codes corresponding to the set numbers
100 to 199.
Parameter No.3442: Sets the M codes corresponding to the set numbers
200 to 299.
Parameter No.3443: Sets the M codes corresponding to the set numbers
300 to 399.
Parameter No.3444: Sets the M codes corresponding to the set numbers
400 to 499.
Each parameter sets the M code that corresponds to the first of the set
numbers allocated to the parameter, thus assigning 100 successive M
codes. For example, when parameter No.3441 = 10000 is set, the M codes
corresponding to the set numbers 100 to 199 are M10000 to M10099.
NOTE
1 When the value 0 is set in a parameter, the specification of
100 added to the value of the previous parameter is
assumed. For example, when No.3441=10000, and
No.3442=0 are specified:
The M codes corresponding to the set numbers 100 to 199
are: M10000 to M10099
The M codes corresponding to the set numbers 200 to 299
are: M10100 to M10199
Specifying 0 for parameter No.3441 has the same effect as
specifying for parameter No.3441 = 100.
2 When a is specified for parameter No.3441, b is specified for
parameter No.3442, c is specified for parameter No.3443,
and d is specified for parameter No.3444, the following
relationships must be satisfied:
a + 99 < b, b + 99 < c, c + 99 < d
