Analog input
Full Name
AI_measure (AI Voltage/Current on Group 1)
Library
LIB\Unipi
Version
V1.1
Description
Important
This function block is no longer needed since IDE 2.1.x and OS v1.6, its functionality has been moved into newly created datapoints AI_1.01, which also includes setting of measurement type.
This block simplifies work with Analog input 1.1 (AI1.1) as Voltage and Current input at all Neuron models and at the follwing moedls of Axon - S105, S115, S155, M205, M505, L205, L505
To save the configuration it is necessary to write log. 1 to the _NVsave_1 in the variable browse while in Debug mode. Please note: This operation saves the actual state of all output including AO, relays. DO, to startup config!
Since firmware v5.0 (variables Vref_1 and so on has value 0) this block is not necessary and its only needed to write to AO_mode and AO_1. However it can be used, backwards compatibility is preserved.
