ST Series User’s Manual
6-22
STATION NO. (0-15)
This is the setup for the ST Station Number mentioned above. The setup range is from 0 to 15, and the only
other restriction is the ST STATION NO. must be unique in the system. If STATION NO.'s are repeated, a
COMMUNICATION ERROR occurs.
6.5.3 Customize Setup (n:1)
The Customize function modifies the n:1 (Multi-link) connection's communication method to make it more
effective. To run communication efficiently, the user should first determine whether they wish to have
Operation or Display priority set for the ST. Based on this, the communication response speed can be
upgraded. (However, this also depends on the screen information displayed.)
PLC PRIORITY
According to how the ST is used, select either Operation priority (OPE.) or Display priority.
• ïOperation
Setup the ST to this option when using the ST mainly as an operation panel. As a result, the ST will com-
mand better touch panel numeric input and switch response times.
Leaving the ST in this mode does not drastically influence the touch panel operation response time of
other STs. The screen display renewal cycle,however, will slow.
•ïDisplay
Setup the ST to this option when using the ST mainly as a monitor screen.
The ST will command a higher display speed as a result; however, the response time for the touch panel's
operations will slow.
• Speed Difference between Display Priority and Operation Priority
When using the Mitsubishi Electric Corp. A3A PLC, with a scan time of 20ms with consecutive addresses
(80 words, not including in the System Area), the difference in reading speed is as shown in the following
graphs.
• The STATION NO. is the number allocated to the particular ST unit. This number is not related
to the Link Unit Machine number.
• In a standard network setup, use the same setup for all connected ST's.
• To increase the display speed, be sure the addresses used are consecutive
addresses. When bit addresses are used, use consecutive to the word units.
