Detailed Settings at Communications Cycle Startup Section 3-5
*3 When the I/O communications manual startup mode is used, it is not after
the power-on but after the remote I/O communications startup switch is
started.
Setting the Registered
Slave Unit Participation
Time This is the time from when the communication cycles for CompoNet Master
Board starts until when a registered Slave Unit is determined to have
participated.
In default, the Registered Slave Unit Participation Time is 30 second in the
data rate of 93.75 kbps but it is 10 seconds in other data rates. It can be set to
an other time.
This setting is disabled when the All Registered Slave Participation Standby
Mode is enabled.
All Registered Slave
Participation Standby
Mode In this mode, the remote I/O communications is stopped until all the registered
Slave Units participate in the network, i.e., while the All Registered Slave Unit
Participating Flag is off. The remote I/O communications starts once all of the
registered Slave Unit participate, i.e., when the All Registered Slave Unit
Participating Flag comes on. All Slave Units can participate in a lesser time
than they do in normal mode or when this mode is disabled.
However, user must be aware that the remote I/O communications does not
start unless all of the registered Slave Units participate.
While this mode is enabled, any settings (including the default of 10 seconds)
based on the Registered Slave Unit Participation Time are disabled.
Communication Cycle
Optimization Function This function is used to disregard any unused communications parts based on
the information on the Registration table, and to optimize the communications
cycle.
3-5-2 Communications Stop Due to Communications Error Function
This function is used to stop entire communications, both I/O communications
and explicit messages, when any one of participating Slave Units has a
communications error. Then the Communications stop due to
communications error occurrence flag, (i.e., the Bit 02 of the StateStatus in
the Basic status group) comes on.
To recover the communications, the CompoNet Master Board must be reset.
This function is enabled by the function CPNT_StartCycleEx in the Windows
operation systems and by the command OPEN_SYSTEMEX for shared
memory access.
3-5-3 I/O Communications Manual Startup Function
This function is used to manually start up the I/O communications.
Slave Units can participate even while the I/O communications stop.
The function is used when one wants to start exchanging I/O data explicitly
from the application.
The function is enabled by the function CPNT_StartCycleEx in the Windows
operation systems and by the command OPEN_SYSTEMEX for shared
memory access.
