Examples Using CompoWay/F Commands Section 6-3
Note 1. Read Controller Attribute (05 03) cannot be executed using CompoWay/F
binary commands. Use CompoWay/F ASCII commands to execute this
service.
2. To write setting data to the variable area for initial settings (variable type
C3) when using EJ1 Temperature Controllers (Write to Variable Area 01
02, variable type C3), first execute Move to Setting Area 1 (Operation Com-
mands 30 05, command code 07).
6-3 Examples Using CompoWay/F Commands
The following example shows the FINS-mini commands, Write to Variable
Area and Read from Variable Area, executed from a CS1W-DRM21 using
CompoWay/F binary commands (embedded in explicit messages).
Operation 1 (Writing
SP)
• This example writes the SP to TC2 (unit number 0, ch1). (The SP is 240.)
The FINS-mini command writes 000240 hex as the SP data for ch1 with
the write start address = 0003 hex, MRC = 01 hex, SRC = 02 hex (Write
to Variable Area), variable type = C1 hex, and write start address = 0003
hex.
• The data is written using the EXPLICIT MESSAGE SEND command
(2801).
• The command data is written in words starting from D01000 in the CPU
Unit's memory, and the response data is stored in DM words starting from
D01200.
• If the command does not end normally, the end code is stored in D01106
and the send command is re-executed.
