1. Overview
1.1 Overview
The SIF-400 is a unit to interface between a PLC and a maximum of 32 units of digital indicating
controllers (DCL-33A, JCx-33A or NCL-13A).
The SIF-400 stores data of the controllers in the PLC register, and exchanges data by reading andresetting the PLC flag.
There are 3 types of memory allocation for the PLC as follows.
• Flexible address selection (Memory allocation per item) (See p.30.)• Flexible address selection (Memory allocation per channel) (See p.38.)• Fixed address (See p.44.)
With Flexible address selection, top address, the number of controllers (DCL-33A, JCx-33A or NCL-13A)
connected with the SIF-400 and Communication item Used/Unused can be designated by the PLC sidesoftware such as ladder software.
Flexible address types can reduce the register capacity that the SIF-400 occupies.
With Fixed address, the predetermined communication items [data quantity for the connected controllers(20 units)] are written to or read from the register area. Initial setting is not necessary on the PLC side.

Register type and address are predetermined depending on the PLC selected during PLC model
selection and PLC memory allocation selection in the Parameter setting mode.
7.1 Flexible address selection (memory allocation per item)
When Mitsubishi MELSEC QR/QW command D register is used, and when PLC memory address is set
to 0 (zero).
7.1.1 Top address and Communication parameter setting completion flags 1, 2 setting
Set top address of register area that SIF-400 uses, to address D0000 of the register.
After the power supply to the SIF-400 is turned on, the SIF-400 keeps reading PLC communication
parameter setting completion flag 1 (D0001) and flag 2 (D0002).
After SIF-400 confirms that D0001 is 4660 (1234H) and D0002 is 22136 (5678H), it recognizes
communication items to be used between SIF-400 and controllers by reading the number ofconnected controllers and the set value of Communication item Used/Unused selection set
in the initial setting table (Section 7.1.2).
Prior to setting Communication parameter setting completion flag 1(D0001) to 4660 and flag 2(D0002)
to 22136, set the number of connected controllers and Communication item Used/Unused first with
the PLC program.
Top address of the register area is set to “nnnn” for explanation.

NoticeAfter set values have been changed, check the error status reading value if there are any errors inthe setting contents. If errors have occurred, correct the data and resend it.
Action details and notes:[AT (auto-tuning)]
When AT (auto-tuning) is performed, P, I, D and ARW values of the controller are written to each
PLC data memory area respectively after AT is finished.
After values are written, AT bit is rewritten to 0 (zero).
[Alarm type]If an alarm type of the controller is changed, the alarm value of the controller automatically
becomes 0 (zero).
Therefore, be sure to set the alarm value again from the PLC after an alarm type is changed.
[Set value change flag]
When setting a Set value change flag, first check that all bits of the set value change flag are
0 (zero), then set the bit of requested setting change item to 1.
If the bit is set to 1 when some bits of the set value change flag are not 0 (zero), setting change
may not be performed normally.
[Set value range]
The SIF-400 does not manage the setting range of all setting items of controllers.
When setting the values from the PLC, be sure to set the value within the setting range.

Set the top address of Register area that SIF-400 uses, to address D0000 of the register.
After the power supply to the SIF-400 is turned ON, the SIF-400 keeps reading PLC communication

After SIF-400 confirms that D0001 is 4660 (1234H) and D0002 is 22136 (5678H), it recognizes
communication items to be used between SIF-400 and Controllers by reading the number ofconnected controllers and the set value of Communication item Used/Unused selection set

For the controller of which SV1 is not changed, thesame value as the current one is set to the assigned
register.
Set the Set value change flag to "2: SV1 change request".
Check if the Set value change flag is cleared to "0",and confirms that setting process is complete.

NoticeAfter changing set values, check the error status reading value if there are any errors in setting
contents. If errors have occurred, correct the data and resend it.
Action details and notes
Action details and notes are the same as those of the flexible address selection (memory
allocation per item). (See p.37.)

7.3 Fixed address
After the power supply to the SIF-400 is turned on, the register to be used is determined by the selectedvalue during PLC model selection and PLC memory allocation selection, and designated setting andreading items are assigned.
For reading item (PLC), data is repeatedly written to the assigned register area.
(Refer to “7.2.7 PLC PV reading” on p.42).
For setting item (PLC), data is set on the controllers by the set value change flag.
(Refer to “7.2.8 Procedures of PLC SV1 writing” on p.43).
Register area allocation for setting and reading items
The following selection conditions are used for explanation.
