2.8 Communication

Warning

All blocks in this category must only be used for status and information purposes.

Software Gateway (out)

Block diagram — Software Gateway (out)

See 1.18 Software Gateway for status information for more info.

This block can encode several signals into a Data and Clock synchronous serial output. Up to 32 signals can be encoded. Connect the Data and Clock outputs to status output blocks to send the information via cable. To deserialize the information, a Software Gateway (in) block can be used.

Inputs

  • 1–32 — the signals to serialize.

Outputs

  • Data — the data output.
  • Clock — the clock output.

Properties

  • Name — changes the name of this block.
  • Half Bit Duration — the time that the clock signal is high for each bit sent.
  • Time between packets — the time between each packet.
  • Inputs — the number of signals to be encoded. This sets the number of input connectors on the block.

Software Gateway (in)

Block diagram — Software Gateway (in)

See 1.18 Software Gateway for status information for more info.

This block can be used to deserialize a synchronous serial stream of data. This can be the output from another Simplifier (see Software Gateway (out)), or from another PLC.

Inputs

  • Data — the synchronous data signal to decode.
  • Clock — the clock to clock the data.

Outputs

  • 1–32 — the decoded data signals.

Properties

  • Name — changes the name of this block.
  • Timeout — if the clock signal is low for this time, the outputs on this block are switched off.
  • Time between packets — specifies how long the pause between packets is.
  • Outputs — the number of signals to decode. This sets how many output signals are on the block.

HOLDX Status Decoder

Block diagram — HOLDX Status Decoder

This block can be used to decode the status signal from a HOLDX R process locking device. It shows when the door is opened/closed, locked/unlocked, and different errors that can occur.

Note

Only one output is active at any given time.

Inputs

  • input — the status signal input. Connect the signal from a Status Input block to this input.

Outputs

  • 1–23 — different status signals. See the manual for HOLDX for the meaning of each signal.

Properties

  • 23 checkboxes to enable/disable which signals are displayed on the block.
