Num Words – This is the number of words to receive from the remote I/O device. Up to four words can
be received from the remote I/O device. The function of these words are described in Table 6.1.
Table 6.1 - Consumed / Produced Parameter Descriptions
Consumed Directed
Digital Data Words
Function Affects
Word 1 (bits 1 to 16) Controls on/off state of digital outputs 1-16. Relay or Digital output SmartStix
Word 2 (bits 17 to 32) Controls on/off state of digital outputs 17-32. Relay or Digital output SmartStix
Word 3 (bits 33 to 48) Specifies whether SmartStix uses default
configuration or values from Word 4.
Relay and Digital input and output
Word 4 (bits 49 to 64) Sets digital inputs / heartbeat and life
expectancy time data.
Relay and Digital input and output
Word 5 (bits 65 to 80) Sets the default state of outputs 1-16. Relay and Digital output
Word 6 (bits 81 to 96) Sets the default state of outputs 17-32. Relay and Digital output
Word 7 (bits 97 to 112) Determines if default state is on or off for
outputs 1-16.
Relay and Digital output
Word 8 (bits 113 to 128) Determines if default state is on or off for
outputs 17-32.

6.4.3
Put Remote I/O Function Block
This function handles sending data to a remote I/O device block obtained from a set of registers specified
by the user. This function passes power flow if the remote I/O device is behavi ng normally. This function
does not pass power flow if the remote I/O device has not sent a heartbeat in 2000 milliseconds. This
function sends heartbeat messages to the output device every 1000 milliseconds. The default remote I/O
operation is to expect heartbeat messages at least every 2000 milliseconds; otherwise the outputs are
turned off (or their configured default state). Data is normally transmitted on change of state or if the
remote I/O device is power-cycled.
A remote I/O device consists of a CsCAN device such as SmartStix Modules that transmit global data and
receive directed network data.
