7. COMMUNICATION DATA LIST
IMR01Y36-E2
49
When data is changed using SRZ loader communication, or when data is changed using DI
of a Z-DIO module, up to 5 minutes (when 31 modules are connected) may be required for
the data to be updated on DeviceNet. In addition, when the engineering setting data in the
SRZ is changed from DeviceNet, up to 5 minutes may be required for the data to be updated
on DeviceNet, depending on the item. [For example, the Set value (SV) and Event set value
when the input type, input scale upper limit, or input scale lower limit is changed]
If you changed the engineering setting data, turn off the power of the COM-JH and then turn
it back on.
Reading/writing operation of undefined attribute ID
When the master read/write data with an undefined attribute ID, an error response is sent by
the slave.
Error response occurs at the following attribute IDs:
[Z-TIO module object (0x64: 64Hex)]
•
form 228 (0x00E4) to 230 (0x00E6)
•
248 (0x00F8) or later
[Z-TIO module extended object (0x65: 65Hex)]
•
43 (0x002B) or later
[Z-DIO module object (0x66: 66Hex)]
•
27 (0x001B) or later
Reading/writing operation of unused controller object (unused item) *
When the master reads/writes data of an unused item, an error response does not occur.
•
For reading, the slave sends default value to the master.
•
For writing, data sent by the master to the slave becomes invalidated. Data of the slave
remains.
* Unused items
•
Controller object is for an optional function not specified at time of order.
Example: Heater break alarm function
•
Controller object is for a function set to “None.”
Example: Event hold action, Event interlock
