A survey of lock automation was conducted at 15 lock sites that use programmable logic controllers PLC by visiting the lock sites and interviewing lockmasters, operators, maintenance personnel, and District Engineers in order to evaluate system components. The lock operating components evaluated were divided into the following categories PLC systems, Operator Interface 01, sensors and switches, and closed circuit television CCTV systems. Where possible, these components were evaluated according to the features available as listed on the manufacturers specification sheets and by the performances of the components based on the experiences of the lockmasters, maintenance personnel, and operators. Draft specifications for controls were proposed based on these and other evaluations.
