Create a screen (PRX) so that the total of continual communication traffic of Master display unit, GP-Viewer EX and Slave display units will not exceed 8090.
If the total continual communication traffic exceeds the upper limit, the slave that has attempted connection will be refused access. In addition, if the upper limit is exceeded by the master display unit only, slave display units cannot be connected.
Use the following process to check the total communication capacity while drawing.
First, for each display unit connected, make sure the number of addresses set for parts and D-Script is 475 or less.
In the [Screen (S)] menu, select [Screen Information (I)], and you can view the number of addresses.
The Master display unit receives the response from the Master display unit, Slave display unit, or GP-Viewer, and if the number of screen addresses does not exceed 475, even if it doesn't take up the entire 475, normal communication traffic is calculated at 475.
Because performance may be degraded if the total exceeds 475, make the total addresses used in parts and D-script on all screens does not exceed 475.
For all screens, ensure that the total of Number of Addresses (Parts) and Number of Addresses (D-Script) does not exceed 475.
Total constant communication traffic is stored in the Master display unit's #H_EtherLink_ConstCommuniMemInfo variable.
Calculate the constant communication traffic of each display unit.
Constant Communication Traffic = 475 + Sound Constant Communication Traffic + Alarm Constant Communication Traffic + Sampling Constant Communication Traffic
When the constant communication traffic of sound, alarms and sampling exceeds the upper limit, an error displays when the project is saved.
GP-Viewer EX constant communication traffic does not include the constant communication traffic from sound, alarms, and sampling.
Calculate the total constant communication traffic of each display unit.
If the total continual communication traffic exceeds the upper limit and connection fails, reduce the sound, alarms or sampling data before transferring, and connect again.
