SC100/200 Series Function Block Application Manual EM-6460-C
1. INTRODUCTION
This manual explains basic programming and processing principles of the SC100/SC200 Series Multi-function PID Control-
ler, and detailed functions of the software function blocks including their coding examples.
These principles are also applicable to MsysNet remote I/O modules connected via peer-to-peer communication network,
with differences in I/O specifications, i.e. field terminals.
It will be a helpful reference tool for the user during programming, debugging and commissioning of the Controller.
Be aware that data and parameters given in the document are only examples, and it is the user’s sole responsibility
to examine and determine the validity of a control strategy design he chooses and its function blocks and opera-
tions.
The SC100/200 Series products are referred to as ‘the Controller’ in this manual if not explained otherwise. Descriptions
applicable to specific models are either mentioned with the particular model numbers, or identified with symbols such as:
SC200/210
The following document will also provide helpful information when using this product:

1.1 SC100/200 MULTI-FUNCTION PID CONTROLLER
■
INPUT & OUTPUT SIGNALS
Physical field terminals: Universal input (DC, T/C, RTD and potentiometer), 2 points
Analog (voltage) input, 4 points (1-5 V DC)
Discrete/pulse input, 5 points
High-speed discrete/pulse input with excitation supply, 1 point
Analog (MV) output, 2 points (4-20 mA DC)
Analog (voltage) output, 2 points (1-5 V DC)
Discrete output, 5 points
Software communication terminals (16 blocks)
SC200/210
I/O signals that can be assigned to each block:
Analog input, 2 points
Analog output, 2 points
Discrete input, 32 points
Discrete output, 32 points
For example, at the maximum of 32 analog I/O signals are usable for remote I/O if all available communication terminal blocks
are assigned with analog signals, and likewise at the maximum of 512 discrete I/O signals are usable if all these blocks are
assigned with discrete signals. Analog and discrete signals can be mixed according to the user’s application needs.
Remote I/O modules are connected via peer-to-peer communication.
■
AVAILABLE SOFTWARE FUNCTION BLOCKS
Control blocks: 2
Computation, timer and counter blocks: 48
Sequential control blocks: 12 (1068 commands in total)
■
SETTING FUNCTION BLOCK PARAMETERS (PROGRAMMING & SET VALUES)
Parameters are set either via the front panel of the Controller or by using the Loop Configuration Builder Software (model:
SFEW3E) on the PC.
■
SAVING PROGRAMMING
Parameters can be uploaded from the Controller to save as a file usable for the SFEW3E or downloaded from the software
program. Maintaining a library of programs will help the user to replace a failed controller with the shortest disruption time.
■
POWER FAILURE
Parameters are stored in the EEPROM, safely in case of a power failure. Running operation data stored in the RAM is not
lost by a brief power failure (less than 10 minutes). A hot start is possible once the power is recovered.
