Detailed Description of the Module
MELSEC-L Series – CANopen
Module ME3CAN1-L
3 – 25
3.5.18
Command Interface (Un\G1000–Un\G1066)
The Command Interface (CIF) can be used to access the Object Dictionary of the local node or a net-
work node. The access is performed by commands for SDO read/write, Emergency Messages, etc.
After writing the command parameter, turn ON Y(n+1)7 to execute the command. If the command
execution is finished, X(n+1)7 will be turned ON (refer to section 3.3.2).
This command uses SDO communication. If the NMT Startup Master is active it can happen that the NMT Startup Master
has already occupied the SDO connection to the remote Node.
During the first initial network startup the NMT Startup Master occupies up to 126 SDO connections at the same time. If an
NMT Slave fails after the initial Network Startup the NMT Startup Master occupies the SDO connection to the specific NMT
Slave. If the NMT Startup master is active for one or more NMT slaves, bit 14 in Un\G25 is ON (Refer to section 3.5.5).
NOTES
The addresses will not be cleared after command execution. The former written transmit data will
be displayed by making new write accesses or using the Display current parameter command
(Refer to section 5.3).
Before a write access to the CIF (command interface), always check if Un\G1000 does not display
FFFF
H
(CIF Busy).
If a write access is made during the CIF (command interface) busy display, a "Command or
Parameter change while CIF was busy" error is generated (Refer to section 5.4.2).
