Supported Protocols

PULSE works with the industrial controllers already running your plant. No need to replace equipment or standardize on a single vendor.

Structured Types (UDT/PDT for Allen-Bradley and Omron)

Native Protocol Drivers

PULSE uses custom-built native drivers for all PLC communication — no third-party middleware, no licensing fees per connection. This means better performance, more control, and one less dependency to worry about.

Each driver is optimized for its specific protocol, with features like bulk reads, connection pooling, and automatic reconnection built in from the start.

Driver Benefits

  • No per-PLC or per-tag licensing fees
  • Bulk read operations for 50-70% faster collection
  • Connection pooling reduces overhead by 80%
  • Automatic reconnection with exponential backoff
  • Protocol-accurate simulation for testing
