6. RKC COMMUNICATION

IMS01J02-E1 81

6.3 Initial Setting (Extended Communication)

This section describes the initialize setting changing procedure when this system is changed to

initialize setting mode. Change the setting correctly in accordance with precautions in each item.

The control unit cannot be switched to the extended communication state at control

start (during control). If it needs to be switched to the above state, first stop the control

by “Control RUN/STOP transfer.”

No control can be started during extended communication. If the control needs to be

re-started, first switch the control unit the normal communication state.

For Control RUN/STOP transfer (Identifier SR) and Initial setting mode (Identifier IN), see

6.2 Communication Identifier List (P. 65).

 Communication Identifier List

Note that there are identifiers which indicate that communication is not possible depending

on the specification.

• Attributes

R/W: Read and Write SR Mini HG SYSTEM ↔ Host computer

WO: Write only SR Mini HG SYSTEM ← Host computer

• Structure

C: Data for each channel L: Data for each event input logic circuit

M: Data for each module U: Data for each unit address

For the data structure, see the 6.1.3 Communication data structure (P. 60).

Data of identifier H3 with H-TIO-/H-CIO-A module is different from H-SIO-A module.

Data is discriminated by channel number (module number).

Identifier H3: For H-CIO-A module....... Cascade DI function selection

For H-SIO-A module ..... DI process selection

For the channel number, see the 8.2.9 Assignment of channels (P. 183).

The Initial setting data should be set according to the application before setting

any parameter related to operation. Once the Initial setting data is set correctly,

those data is not necessary to be changed for the same application under

normal conditions. If they are changed unnecessarily, it may result in

malfunction or failure of the instrument. RKC will not bear any responsibility for

malfunction or failure as a result of improper changes in the Initial setting.
