The event counter is active for RF firmware revision 5.3 or higher.
In the default position (OFF), the input 1 through 6 control the
tower lights. When DIP switch 3 is ON, input 5 wire is the counter input and input 6 wire is disabled. Registers 5 and 6 store the 32-
bit synchronous counter count. Inputs 5 and 6 are independent from the lights and will not drive any lights they are wired to. Input
wires 1 through 4 function normally.
DIP Switch 3: Event Counter
900 MHz Models and 2.4 GHz Models
OFF *
Default I/O operation
ON
8-pin Models: Configure input 5 as a 32-bit synchronous counter at a maximum frequency of 20 Hz; disable
input 6 (the counter requires two registers)
5-Pin Models: Configure input 3 as a 32-bit synchronous counter at a maximum frequency of 20 Hz
The event counter is active for RF firmware revision 5.3 or higher.
For the 8-pin models: In the default position (OFF), inputs 1 through 6 control the tower lights. When DIP switch 3 is ON, input 5
wire is the counter input and input 6 wire is disabled. Registers 5 and 6 store the 32-bit synchronous counter count. Inputs 5 and 6
are independent from the lights and will not drive any lights they are wired to. Inputs 1 through 4 function normally.
For the 5-pin models: In the default position (OFF), inputs 1 through 3 control the tower lights. When DIP switch 3 is ON, input 3
wire is the counter input. Registers 3 and 4 store the 32-bit synchronous counter count. Input 3 is independent from the lights and
will not drive any lights they are wired to. Inputs 1 and 2 function normally.
DIP Switch 4: Bit Packing I/O
900 MHz Models and 2.4 GHz Models
OFF *
Default I/O operation
ON
Bit-packed I/O with all inputs in Modbus register 1 and all outputs in Modbus register 9. All other Modbus
registers are disabled.
Bit packing is active for RF firmware revision 5.8 or higher.
Bit packing uses a single register, or range of contiguous registers, to
represent I/O values. This allows you to read or write multiple I/O values with a single Modbus message. Input 1 is stored in the
least significant bit of register 1. Output 1 is stored in the least significant bit of register 9.
Event Counter
To use the event counter, the measured (logic high) signal must be greater
than or equal to 25 ms. The 32-bit count is stored in I/O registers 5 and 6.
To zero out (clear) the event counter,
•
Map an input/button on a Gateway to Node register 14 to clear the
counter when the input/button is activated; or
•
From a host system, write a 1 (the output must transition from a zero
to a one to reset the counter) to Node register 14 or write a 5424
(0x1530) to Node control register 15.
RF firmware revision 5.3 or higher (on all products released after 3/20/2015) is
required to use this feature.
