• The total number of write data bytes is 2
• Refer to the table of DeviceNet explicit messages set values and measure-
ment values for details on addresses and variable types of write set values
and measurement values.
• If there is an error in even one part of the data being written, all of the data
written at the same time will not be saved in the E5ZE.
FINS command 2801 is sent using CMND(194/490) or IOWR(223) to send
DeviceNet explicit messages from an OMRON PC Master Unit. For details,
refer to the DeviceNet (CompoBus/D) Operation Manual (Cat. No. W267) or
the CS1W - DRM21 DeviceNet Unit Operation Manual (Cat. No. W380).
When DeviceNet explicit message communications are used with the E5ZE,
there are settings that are specific to the control data for CMND(194/490) and
IOWR(223) instructions that must be set, as shown next.
For details on both instructions and their applications, refer to the DeviceNet
(CompoBus/D) Operation Manual (Cat. No. W267).
The control data for the CMND(194/490) instructions is as follows:
Word
15 12 11
C Number of command data bytes
C+1 Number of response data bytes
C+2 0
C+3 Destination node address
(Local node DeviceNet Master
MAC ID)
C+4 0 (response
required)
C+5 Response monitoring time (0000 to FFFF), in 0.1 s increments (except 0000
that is 2 s)
The control data for the IOWR(223) instruction is as follows:
Word
15
C 0/1 0 Destination address
(Local node DeviceNet
Master MAC ID)
Bit 15 is used to set whether a response is required or not. If bit 15 is set to 0,
a response is required and if the bit is set to 1, a response is not required. Set
this bit to 0 (response required).
Bits 8 to 13 are used to set the destination node address (E5ZE node
address), and bits 0 to 7 are used to set the destination Unit address (the local
node DeviceNet Master Special I/O Unit number or FE).
