(1) Zeroing is carried out using the method designated in the zeroing data (see
Section 7.21.1).
Refer to the following sections for details about the zeroing methods:
• Proximity dog method ...................... Section 7.21.2
• Count method .................................. Section 7.21.3
• Data set method............................... Section 7.21.4
(1) If the following circuit conducts zeroing using the proximity dog method after the
PLC ready flag (M2000) turns ON but before the PCPU ready flag (M9074)
turns ON, another zeroing request is issued after zeroing is complete.
Therefore, apply interlock conditions to M9074 and M1602+20n (in-position
signal) when carrying out a zeroing. (See program example.)
