TMEIC Control System
Panama Balboa Port 3 STS Crane Upgrade Project
Project Summary：The crane used GE T250Wi series drives and 9030 series PLC for control. The communication between the drive and PLC was facilitated using the IS bus method. The 9030 series PLC and ISC controller, along with other devices, have been discontinued. To ensure the normal operation of the equipment, we remove the ISC controller and upgrade the PLC to the RX3I series, with the communication method being changed to EGD.
Kingston Freeport Terminal Ltd 4 STS Crane Upgrade Project
