5.2.3 Control Relays
Control Relays are used for internal storage of discrete (Boolean) data. Control Relays are not
associated with the physical I/O. The number of control relays supported varies with the
controller model. See Section 1.20.
Control Relays may be retentive or non-retentive. Retentive relays hold their value over a power
cycle, as long as the battery is good. The address of the control relay determines whether it is
non-retentive or retentive. See the table below.
Non- Retentive Retentive
C1 – C768 C769 – C1024
C1025 – C1792 C1793 – C2048
C2049 – C2816 C2817 – C3072
C3073 – C3840 C3841 – C4096
C4097 – C4864 C4865 – C5120
C5121 – C5888 C5889 – C6144
C6145 – C6912 C6913 – C7168
C7169 – C7936 C7937 – C10240
C10241 – C32768
C32769 – C56320
See Note 1
NOTE 1: C400 Models using firmware Version 8.01 and above support these additional control
relays. PLC Workshop users will require Workshop version 4.8 and above to utilize the
additional control relays. APT users can use Jumper A to access the additional control relays.
See Section 2.4. TISOFT programming software cannot access the additional control relays.
5.2.4 Status Words
Status Words are used to provide information about the controller operation. Because Status
Words can be read by user logic, they can be used to condition the operation of the controller.
In addition, the Status Words can be accessed by programming or supervisory control software.
See APPENDIX B. – SYSTEM STATUS WORDS for a description of the System Status Words.
5.2.5 Configuration Data
The following configuration data is maintained in the battery backed memory:
•
I/O Configuration
The I/O configuration data includes the I/O Configuration, which associates the logical I/O
addresses with the physical I/O points, and the base enable status.
•
Memory Configuration
The memory configuration contains the user memory allocation for each of the User
Program elements listed in Section 5.2.1 above.
•
Profibus Configuration
The Profibus configuration includes the Profibus parameter sets, which define the
characteristics of the Profibus bus and slaves; the operational parameters, and the Profibus
I/O configuration table.
•
Scan Configuration
The scan configuration includes the scan type, the scan time, the task codes per scan, the
scan watchdog value, and the analog scan time slice configuration. See CHAPTER 6 for a
description of the CTI 2500 scan.
