LOG (FieldPoint Log Block) (FP-3000 Specific)

The LOG block contains a log of error conditions and events detected by

the device as it operates.

STAT (FieldPoint Statistics Block) (FP-3000 Specific)

The STAT block contains a set of parameters that can be used to examine

how the device is performing. It contains statistics describing the

performance of local function blocks and the network interface.

Function Blocks and FieldPoint Modules

The FP-3000 supports a wide variety of I/O channels, each with different

types of configuration information. For example, a thermocouple channel

includes parameters for thermocouple type and has ranges for different

temperatures; a current loop channel includes parameters for filter

frequency and has a different group of available ranges to chose from.

Because of these differences in parameters, the FP-3000 has a block

specific to each type of channel it supports. To use a thermocouple

connected to an I/O channel on an FP-TC-120 module, the FP-3000

provides a FP-TC-120 AI Block. This block is a standard Analog Input

block augmented with parameters specific to the thermocouple channel on

the FP-TC-120.

Binary Open/Close

(BINARY_OP/BINARY_CL)BINARY_OP only functions when ENABLE_OP has a value of

Discrete_State_1. BINARY_CL only functions when ENABLE_CL

has a value of Discrete_State_1. If both BINARY_OP and

BINARY_CL are set and enabled, neither one takes effect.

Operator Command

(OP_CMD_CXO)OP_CMD_CXO is a contained bit string parameter that has a bit for

Open and a bit for Close. Open only functions when ENABLE_OP has

a value of Discrete_State_1. Close only functions when

ENABLE_CL has a value of Discrete_State_1. If both Open and

Close are set and enabled, neither one takes effect.
