Interface Specifics Section 5-4
5-4 Interface Specifics
This section describes the function of individual bits and words in the PLC
Interface Area. Timing charts and programming examples list the addresses
for task 1 and the X axis and are given in the following form.
Bit and Word Addresses
“n” is the first word allocated to the MC Unit as a PLC Interface Area and it
can be calculated from the unit number set on the front of the Unit as follows:
n = CIO 2000 + 10 x unit number
n+42
n+43 Z-axis
Status Flags 00 to
15 Z-axis present position (32-bit signed data)
The present position of the reference coordinate system is output. The position
of the decimal point is determined by the system parameter settings.
n+42: Rightmost 16 bits, n+43: Leftmost 16 bits
Refer to X-axis present position in n+36 and n+37.
318
n+44 00 to
15 Z-axis Status
Refer to X-axis Status in n+38.
318
n+45
n+46 U-axis
Status Flags 00 to
15 U-axis present position (32-bit signed data)
The present position of the reference coordinate system is output. The position
of the decimal point is determined by the system parameter settings.
n+42: Rightmost 16 bits, n+43: Leftmost 16 bits
Refer to X-axis present position in n+36 and n+37.
318
n+47 00 to
15 U-axis Status
Refer to X-axis Status in n+38.
318
n+48
n+49 Reserved for the system. ---
CS1W-MC421 PLC Interface Area Inputs (MC Unit to CPU Unit) n = CIO 2000 + 10 x unit number (words)
Word Contents Bit Description Page
Autoloading Error Reset
(n, 05)
Autoloading Error
(n+10, 05/n+18, 05)
If only one address is given, it is the same for the CS1W-MC221 and
CS1W-MC421. The word is listed first, followed by the bit. This exam-
ple shows that bit 05 of word n is the Autoloading Reset Bit.
If two addresses are given, the first one is for the CS1W-MC221 and
the second one is for the CS1W-MC421. This example shows that
the Autoloading Error Flag is bit 05 of word n+10 for the CS1W-
MC221 and bit 05 of word n+18 for the CS1W-MC421.
