4-24.1 Connection with PLCHow to connect with PLC・Connecting between one GT and one PLC via 1:1 communication・Connecting between one GT and multiple PLCs via 1:N communication (PLC multipleconnection)・Connecting between one PLC and multiple GTs via 1:N communication (GT link)・Connecting using the general-purpose serial communication mode・ As for the 5 V DC-type GT01, power can be supplied with a communication cable only.4.1.1 PLC Multiple ConnectionPLC multiple connection function is a function that enables more than one PLCs to connect with one GT.4.1.2 GT Link ConnectionGT link function is a function that enables more than one GT to connect with one PLC.Wiring of Power SupplyIt takes more than 5 seconds for all GT units to be operable after turning on the power supply of GT.(The time varies according to conditions and the number of connected GT units.)As for the power supply of GT, it is recommended to use the wiring that enables multiple GTunits to be simultaneously turned on.If the power supplies of multiple GT units cannot be simultaneously turned on after turning on the powersupply of devices such as a PLC, an error message will be displayed and it may take some time to makecommunication to be established.(The error display disappears when all the GT units become operable.)Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.ctiautomation.net - Email: info@ctiautomation.net
