Chapter 4. Functions
Pattern operations in which the SP changes over time, as shown in the figure, are available.
A pattern consists of multiple segments, and each segment is determined by the specified SP and time. For each
segment, a PID group number, G.SOAK (guaranteed soak), and a segment event can also be set.
The same pattern can be shared among all loops (up to four loops). The pattern numbers selected for each loop can
be the same or different. Although each loop can be operated independently, it is also possible to synchronize their
operation using DI functions or logical operations.

Handling Precautions
• 1 - 6 Operation Modes (p.1-23)
• 4 - 8 DI (Digital Input) (p.4-49)
• Pattern start number (p.4-46)
• If the version of the MAIN block firmware is earlier than 6.x.x (where x stands
for any number), the pattern operation function is not available.
• States such as the RUN-HOLD mode, RUN-END mode, cycle, and pattern link
are not maintained if a power failure occurs. When the power is restored, the
device starts operation in the RUN mode from segment 1 of the pattern start
number. If PV start is set to enabled, PV start is executed at this point. The
READY mode is maintained even when a power failure occurs.
• For control loops on either the master or the slave side of the internal cascade,
only the constant value operation mode is available, so the mode cannot be
switched to pattern operation.
