Perils of a DIY Distributed Control
Are you using PLCs to do the job of a DCS? Tired
of "patching in" software to get your PLC to perform complicated control
functions? Are licensing issue of hurting your plant productivity?
Control system engineers, maintenance managers, and plant managers are taking
a fresh look at the trade-offs between a DCS and a PLC-based control system
architecture for their control system upgrades.
Honeywell's whitepaper, The Perils of a DIY
Distributed Control System, walks you through the key issues of systems
upgrades: network and control performance, HMI graphics, control algorithms,
application software, data management, batch automation, open connectivity,
simulation technology, and process history.
