OCS-I/O Modules

OCS-I/O via CsCAN

Horner OCS-I/O is a Remote I/O option that connects via CsCAN Network to all Horner OCS host Controllers that includes XL series, Micro OCS series, XL Prime , and XL Canvas Series.

OCS-I/O hardware consists of a Horner HE959CNX116 CsCAN Base Unit with up to 7 Horner OCS I/O Modules stacked onto it. Controllers which have CsCAN port supports CsCAN I/O Configuration, including OCS-I/O modules.

Note: Each Host Controller can access up to 16 OCS-I/O Base Units.

OCS-I/O Configuration

To configure OCS-I/O, from Hardware Configuration dialog, select the model that supports CsCAN I/O and click on the ‘CsCAN I/O’ tab.

Select CAN1 (CsCAN) I/O to open the screen below:

Selecting Add opens the following dialog:

The CsCAN I/O supports Smart Rail, OCSIO, Smart Stix, Smart Block & other types of modules.

Selecting OCSIO tab brings up the below displayed window:

Select HE959CNX116 in the OCS-I/O tab and then click the OK button, which opens the Configure OCS-I/O dialog, as shown below:

Node Details

Base Name: Any descriptive text (0 to 15 characters).

Network ID: OCS-I/O Base Unit Network ID (1 to 79). NOTE: In single OCS-I/O base configuration change in Network ID requires power cycling of the base to re-establish communication with the host controller.

Enable OCS-I/O: When this option is checked Input/Output data from Host controller will get transmitted to OCSIO. If the option is unchecked Input /Output data will NOT get transmitted to OCSIO but communication between the Host controller and OCS-I/O will be healthy.

Device UUID: Each OCS-I/O base requires a Unique ID to establish communication with the host controller. In case of Single Base OCS-I/O entering UUID is not required, host controller can automatically assign that. In case of Multiple base configurations, it is Mandatory to enter UUID of each base.

Status Register: Host controller reports the communication status of the OCSIO Base unit and stacked IO Modules in Fifteen consecutive registers

Digital Inputs Start: Start of OCS register block where digital input data will be stored

Digital Outputs Start: Start of OCS register block containing source data for digital outputs

Analog Inputs Start: Start of OCS register block where analog input data will be stored

Analog Outputs Start: Start of OCS register block containing source data for analog outputs

Comm Timeout: Maximum time Base Unit or Host Controller will wait to indicate / act on loss of communication (40 to 255000 mS).

Onboard I/O

OCS-I/O base supports 2 Digital/Analog Inputs, 1 universal Analog Input and 1 Analog Output. Configuration for this Inputs/outputs are done by selecting Onboard I/O tab.

Selecting Onboard I/O displays below window:

Data Range: Select Data range for the Analog Input. Data range depends on the Input type selected.

Data Range
Input Type	Data Range
0-20mA	0~4000, -2000~2000,0~1000,0~2000,0~32000
4-20mA	0~4000, -2000~2000,0~1000,400~2000,0~32000
0-10V	0~4000, -2000~2000,0~1000,0~32000

Thermocouple J, K, T, E, N, R, S, B	Degree Celsius and Fahrenheit
PT100 and PT1000	Degree Celsius and Fahrenheit

Filter Constant: Analog Inputs can be filtered Digitally with this Filter constant values. Valid filter values are 0 to 7.

Alarm: OCS-I/O status register has Three bits to indicate Alarm condition of Analog Inputs. User must configure values for Low Low, Low, High and High High to trigger alarm. Once the Analog Input value reaches the Alarm values then the Alarm bit in status Register will get triggered.

Alarm Bit Registers
ALM Warning	ALM1	ALM0	Alarm
1	0	0	LL
0	0	1	L
0	0	0	Normal
0	1	0	H
1	1	1	HH

Alarm values can be given as a fixed values or through Register. Four consecutive Registers are used for providing alarm values through Registers. See also: System Register Tables

Config Register: Analog Input Type, Data Range, Filter values can be selected through Register. Configure Register in this field and user must move predefined values to the register to select the required Input type, range, and filter.

Note: When Analog Input is configured through Register and Alarm is used as fixed value means, whenever the user changes the data range configuration by changing the dynamic value, the fixed alarm values remain the same and lead to alarm discrepancy. It is recommended to configure Alarm values through Registers if the Universal Analog Input configuration is through Registers.

Auto Populate All

Cscape has the feature to automatically detect the connected OCS-I/O CNX base and the attached I/O Modules by using Auto Populate All .

In Add Cscan I/O dialog, click on “Auto Populate All” to detect the connected OCS I/O bases in the Network. Base information will get fetched to Cscape and it will get added in the configuration.

Auto Populate I/O

Cscape also has the feature to automatically detect the connected I/O modules to the Base using Auto Populate I/O. The OCS-I/O CNX base must be manually configured and communication between host controller and base must be established to detect the I/O modules connected to Base.

Click on Auto Populate I/O to detect the I/O modules connected to the Base and once detected the Modules will get added to the configuration in Cscape.

Note: Auto Populate I/O will delete the currently configured I/O modules in Cscape and will get updated with detected I/O modules.
