Unintended modifications to MSR300 Systems are prevented by design. The system
configuration is automatically checked when it is first started up, and this information is
stored in non-volatile memory (EEPROM) in the Base Module. Whenever the system is
started up (or restarted) thereafter, the current system configuration is checked against
the stored configuration. If a discrepancy is detected, a fault response is immediately
generated, with appropriate diagnostic indication and output (see setup details in Chapter
7.3).
The MSR300 System is suitable for safety monitoring and control of robot cells, with or
without additional safe areas. The special MSR329 Muting Lamp Module is available for
this.
Special logic functions can be implemented in MSR300 Systems (see Section 5.2 and
Chapter 8).
3.3 MSR300 Modules: Summary
Brief descriptions of the MSR300 Series Modules are given in this section, followed by
the specifications of the modules in tabular format in the next section. Details of the
Modules are given in Chapter 4.
MSR310 Base Module:
Functions:
System control, safety and auxiliary output contacts,
supervision of bus-connected input and output modules,
monitoring of reset and feedback loops
Auxiliary outputs:
3 solid-state switch outputs for signaling the states of output
groups
Serial data interfaces:
Two RS232 ports (bi-directional and uni-directional)
The MSR310 Base Module has two microprocessors for redundancy and supervision of
I/O modules and one for interface and diagnostic operations. Comprehensive diagnostic
information is available through LED indicators, auxiliary solid-state switch outputs and a
serial data interface.
MSR320 Input Module:
Functions:
Processing inputs from various safety sensing devices,
assignment of sensing inputs to output switching groups by
means of rotary coded switches.
Inputs:
2 safety inputs (each module)
2 auxiliary outputs (if third channel is not used)
