- 243 -
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
