2. COMMUNICATION SETTING OF COM-MY
Set communication setting before mounting and wiring of the COM-MY.
CAUTION
Do not separate the module mainframe from the base with the power turned on.
If so, instrument failure may result.
To avoid problems or malfunction, do not duplicate an address on the same
communication line.
2.1 Station Address and Transmission Bytes Setting
Set a station address and number of transmission bytes of MECHATROLINK. For this
setting, use a small blade screwdriver.

COMMUNICATION SETTING OF SRZ FUNCTION MODULE
3.1 Address Setting of SRZ Function Module
Only make the module address setting to make the Z-TIO, Z-DIO and Z-CT module
communication settings. The SRZ unit performs internal communication (RS-485) between
the COM-MY and the function module (Z-TIO, Z-DIO, Z-CT module), so the
communication protocol, communication speed and data bit configuration do not need to
be set. A module address is set for each function module type.
To avoid problems or malfunction, do not duplicate an address in a function
module of the same type on the same communication line.
3.2 For the SRZ Unit's Channel
Setting the function module (Z-TIO, Z-DIO, Z-CT module) address determines the channel
number used for communication. To each function module address, the relevant channel
is assigned.
Each channel number can be calculated from the following equation.
Channel number of communication =

Exception operation
When power is turned ON
During initialization after the power is turned on, CMDRDY bit (b2) of STATUS is 0
(commands cannot be accepted). If an I/O write is attempted at this time, it will be
disregarded. If an I/O read is attempted, 0 will be returned.
When a device error occurs
When ALARM (error code) is other than 00H, or the WARNG bit (b1) or ALARM bit (b1) of
STATUS is 1 (error), this indicates that the device is in an error condition. If an I/O write is
attempted at this time, it will be disregarded. If an I/O read is attempted, 0 will be returned.
