FC 132 - Analog Input / Slave

The analog input/slave function code reads five analog inputs from an IMFEC12 Analog Input Slave or an IMFEC11 Field Bus Slave. Three analog input/slave function codes are required to utilize all 15 input channels on the module. When these function blocks are linked, only the status output of the primary block will be functional.

 

Function code 132 is also used with ABB FSK smart protocol and FSK bus applications. In the case of bus mode and multivariable bus mode applications, three instances of function code 132 are needed whenever there are 15 variables. This function block has six outputs. The first five are the inputs from the analog input module. The sixth output is the status of the analog input module.

 

The control system must be carefully evaluated to establish default values that will prevent personal injury and/or property damage in case of module failure.

132.1  Explanation

 

132.1.1 Specifications

 

S1

Address of the analog input module.

 

S2

Block address of the next analog input block. The first block in the list is the master block. The rest of the blocks are under its control. Use the default value for the last block.

 

S3

Can be set to allow the module to continue to operate if there is an input module problem.

0 = trip master module

1 = continue to operate

 

S4

Defines the input signal type of the first input from the module.

0 = 4 to 20 milliamps, also used for FSK digital mode

1 = 1 to 5 VDC

2 = -10 to +10 VDC

3 = 0 to +1 VDC

4 = 0 to +5 VDC

5 = 0 to +10 VDC

 

S5

Defines the low limit of the first input in engineering units.

 

S6

Defines the range of the first input in engineering units. If this specification is set to zero, the input is considered unused.

 

NOTE: For any channel that is connected to an AVS smart positioner the low limit (S5) must be set to zero and the range value (S6) must equal 100. However, if the normal operating range of any of the outputs are expected to include numbers less than -5 or more than +105, the range value (S6) should equal 1 and the output of that channel should be treated as a normalized value. To unormalize the value, send the output of the block into a multiply block and multiply by 100. This is to get around the bad quality state which is automatically generated by function code 132 when the value is outside the -5 to +105 range.

 

S7 through S18

Define the input signal type, low limit and range for the other channels on the analog input module.

 

S19 and S20

Spare parameters.

 

132.2   Application

 

Figure 132-1 shows analog input blocks linked together. The inputs must be numbered consecutively.

 

NOTE: When using smartport, block numbering is critical when configuring analog inputs from smart transmitters. The block numbers for the three analog input/slave function codes must be numbered consecutively and the 15 smart field device definition function codes associated with the inputs must be numbered consecutive immediately following the inputs.
