DESCRIPTIONS

RUN Contact Output (LED) Behaviors
Input module
The LED for the Input Modules turns ON when the network is on-line.
When there is an abnormality in the network, the LED turns OFF.
The network is reconfigured after an abnormality.
Output module
The LED for the Output Modules turns ON when the network is on-line and the module receives data from the corresponding Input Module.
When there is an abnormality in the network or there is no data receiving, the LED turns OFF.
Station Number (Address)
A) 1 input module and X output modules:
Match the address for input and output modules.
B) Computer interface:
Set address numbers to correspond with the computer as output module.
Transmission Time
Integrate all the transmission time for each process input module in the system.
• Analog input 16 points: 24 msec.
An analog module does not transmit all its signals in serial but does 1 point per each cycle.  For example, when 1 contact input module (DLA1, 32 points) and 1 analog input module (16 points) are connected, 32-point contact signal and 1 point analog signal are transmitted in turn.
One cycle time is therefore calculated as:

  32 points x 1.5 msec. + 24 msec. = 72 msec.
This method is beneficial for giving a priority to contact signals which vary rapidly.
Applicable models for use with 61S Input Module
• 61S-162 (Ao 16 points)
• DLA1-xM1 (Ao 32 points; only the top 16 out of 32 are used)
