53SL5100 Single Loop Controller Rev. 1 Firmware
53SL5100A Single Loop Controller - Addendum 1
1.0 APPLICABLE DOCUMENTATION
This addenda publication contains additional information applicable to the Micro-DCI™ 53SL5100A
Instruction Bulletin, SIngle Loop Controller.
1.1 SCOPE OF CHANGES
Contact Closure Output 1 (CCO-1) functionality is added to the 53SL5100A Single Loop Controller as a
result of Revision 1 to the firmware EPROM. CCO-1 operates with Control Strategies 1, 3 and 4 of the
Single Loop Controller. These Control Strategies are respectively the Single Loop (PID) Controller, Ratio
(PID) Controller and Automatic/Manual Station.
Also, as a result of Revision 1 to the firmware EPROM, there are Process Alarm selectable assignments
now available for Contact Closure Output 0 (CCO-0). (The newly added CCO-1 does not have selectable
Process Alarm assignments, but is dedicated only to Process Alarm 2 [PA2].)
2.0 CONTACT CLOSURE OUTPUT 1 (CCO-1)
SPECIFICATIONS
CCO-1 is a solid state device that can be configured as a normally open or normally closed switch. It has a
maximum voltage rating of 30 V dc and a maximum current rating of 50 mA.
2.1 CONTACT CLOSURE OUTPUT 1 (CCO-1) WIRING CONNECTIONS
Connection to CCO-1 is made at pin 18 of TB1. CCO-1 is referenced to power common (pins 11, 14 and
17 of TB1 are power common pins). When CCO-1 is connected to an inductive load, an external arc
suppression network is required for contact protection.
2.2 CONTACT CLOSURE OUTPUT 1 (CCO-1) DATAPOINT MODULE
Datapoint assignments that control CCO-1 operation are described in Table 1 as follows:
Table 1. Contact Closure Output Module 1 (CCO-1)
Title Symbol
CCO0
Datapoint
Default Attribute
Purpose: This module allows the action of CCO-1 to be reversed (normally a closed contact = 1, but can
be changed to = 0).
Contact Output
(Display Only) CCO1 L025 0 If CCO-1 = 0 and OINV = 0, then it is open.
If CCO-1 = 0 and OINV = 1 then it is closed.
If CCO-1 = 1 and OINV = 0 then it is closed.
If CCO-1 = 1 and OINV = 1 then it is open.
Contact Output
Invert OINV1 L289 0 As shown above, it reverses the action of CCO-1
datapoint.
Tag Name COTAG1 A281 CCO1 It is an assignable 10 character name for the contact
control output.
