Achieving Efficiency and Reliability with Wireless Communication

In the challenging environment of a sea shore facility with harsh, humid climate conditions, a critical application involved the remote control and interlocking of Stacker-Reclaimers, vital machines in the material handling section. These machines, three pairs in total, played a pivotal role in preparing and managing raw material stockpiles essential for cement production. To facilitate seamless communication, Programmable Logic Controllers (PLCs) were employed on these moving machines, utilizing the DF1 protocol. Meanwhile, in Load Center 1 (LC1) at the field’s forefront, a Siemens S7-400 PLC with Profibus protocol was stationed.
