The two-channel modules in the K60 compact series collect or supply analog signals locally. These modules are linked to a higher-level programmable controller via an AS-Interface master acc. to Specification 2.1.

The analog modules are grouped into five categories:

•Input module for two current sensors

•Input module for two voltage sensors

•Input module for two temperature sensors

•Output module for two current actuators

•Output module for two voltage actuators

The input and output channels are galvanically isolated from the AS-Interface network. If sensors with a greater power consump- tion are to be connected, instead of the internal supply, more power can be supplied via the auxiliary voltage.

The modules, complete with their technical specifications and detailed operating instructions, are presented in the manual in considerable detail. This is supplemented with function block examples.

Data transfer in accordance with the 7.3/7.4 analog profile (simplified)

In the case of the 7.3/7.4 analog profile, at least seven AS-Inter-

6

face cycles are executed until data transfer is complete. For this

 

purpose, a master with the expanded specification V2.1

 

must be used.

 

In the case of input modules, the complete analog value is then

 

available in the AS-Interface master. Preprocessing takes place

 

in the master.

 

The user program fetches the analog value as one value into the

 

user program on the next system function call. The analog value

 

is therefore updated extremely quickly.

 

This procedure takes place in reverse order in the case of output

 

modules.
