BOOK 1 SECTION 1 FUNCTION CODES – INTRODUCTION
Function Codes – Introduction HOW TO USE THIS BOOK This book is meant for users of Bailey SLC, CLC controllers who are migrating to the new generation MicroMod MOD 30ML controllers. Though both Bailey controllers and MicroMod controllers are microprocessor based programmable controllers, the configuration and the programming approach to them is different. This book should help a Bailey user to understand the MOD 30ML controller with minimum time spent in learning the new technology.
Command Series Migration to MOD 30ML Function Codes – Introduction The user database is configurable and writable to make the instrument perform a variety of executable functions. The basic logical element of the database is a function block. Function blocks are grouped to form multiple process loops. Loops in turn are grouped into sets that are scanned (executed) at the same rate. Up to five different scan rates can be configured through the interface block.

Command Series Migration to MOD 30ML Function Codes – Introduction FUNCTION BLOCK EXECUTION ORDER: The order in which the blocks in the database are executed is known as the Function Block execution order. The execution order is set at the top level where the loop compounds are added to the database. The default execution order for the loop compounds is the order in which they are placed in the database.
Command Series Migration to MOD 30ML Function Codes – Introduction COMPOUNDS: Function blocks in a database can be compounded (grouped) into a single group. This may be done to functionally or visually organize the blocks in a database. Compounds can be created at the top level or inside loop compounds. To compound a set of function blocks, first select them and then select Objects – Compound from the ViZapp menu bar.

Function Code 156 – Auto Bias Station GENERAL DESCRIPTION The PID with Auto Bias Station is basically a Manual/Auto station that performs Manual / Auto function for the input. When the controller is in AUTO, the output matches the input. The user can change the output by forcing the controller to MAN (manual) mode. The Auto Bias function adds an automatic bias to the output when the controller is switched from Manual to Auto thereby ensuring a bump-less transfer.

Function Code 165 - Moving Average GENERAL DESCRIPTION The moving average function code computes a moving average from n samples taken at a defined interval. The sample buffer fills with an input value at the end of each cycle. At every sample interval, the current input value replaces the oldest value in the buffer. At each sample interval, a new average is calculated. UTILIZATION The MOD 30ML/MODCELL compound FC165 uses Ex (expression) and Timer blocks. Figure 165 .1.
