Monitoring ingress at entry points is critical for ensuring facility security, operational continuity, and regulatory compliance. By consistently tracking factors such as access frequency, identity verification, irregular entry times, and failed attempts, organizations can quickly detect anomalies and respond to potential threats.
Ingress Monitoring Methods with TPS Devices
Use a Digital Input Tibbit
Detects: Digital input.
Digital input Tibbits, such as #00, #04 and #54 allow you to easily measure digital inputs and perform cycle counting with TPS devices. A terminal block connector Tibbit such as #20 or #21 is also required. For example, Tibbit #54 has four dry contact input lines; applying ground to any of these four lines updates its boolean variable to 0, and in AppBlocks you can configure this variable changing event to add door entry records to logs, or trigger further logic such as security alerts.

Use a Tibbo Modbus Sensor aka Bus Probe (BP)
Detects: Digital input.
Tibbo Bus Probe BP#06, allows you to detect digital input at significant distances from a TPS device. The probe communicates over RS485 using the Modbus RTU protocol. You can place the sensor as far as 50 meters (160') away, and multiple probes can share a single RS485 bus. Module Tibbit #05 handles RS485 signals, and Connector Tibbit #20 (or #21) provides the necessary terminal blocks.
Schematic:
Pros:
- May be placed up to 50 m (160') from the TPS device.
- Multiple Bus Probes can operate on a single RS485 bus.
